立体影像显示装置及其制造方法Stereoscopic image display device and manufacturing method thereof

技术领域technical field

本发明涉及不使用特殊的眼镜就可以进行立体影像显示的液晶视差隔板方式的立体影像显示装置及其制造方法，尤其涉及考虑了由背光产生的热导致的基板的热膨胀的立体影像显示装置及其制造方法。The present invention relates to a liquid crystal parallax barrier type stereoscopic image display device capable of displaying a stereoscopic image without using special glasses, and a manufacturing method thereof, and more particularly to a stereoscopic image display device and a method for producing a stereoscopic image that takes into account thermal expansion of a substrate due to heat generated by a backlight. its method of manufacture.

背景技术Background technique

过去，作为不使用特殊的眼镜而显示立体影像的方法，公知有双凸透镜方式、视差隔板(パララックスバリア)方式、将光源狭缝化的方式等方式。Conventionally, as methods of displaying stereoscopic images without using special glasses, methods such as a lenticular lens method, a parallax barrier method, and a method in which a light source is slitted are known.

图4是表示视差隔板方式的立体影像显示的原理的示意图。观察者所观察的影像在液晶显示面板50上形成。为了能够进行立体观察，在上述液晶显示面板50上，显示左眼用影像的左眼用像素L和显示右眼用影像的右眼用像素R交替配置而形成。左眼用像素L和右眼用像素R例如可以用左眼用和右眼用的2台摄像机同时进行摄影而得到，或者从一个图像数据通过逻辑运算而计算出。在这样得到的两像素中，包括人类通过两眼视差而进行立体感觉所需的视差信息。FIG. 4 is a schematic diagram illustrating the principle of a three-dimensional video display using a parallax barrier method. The image observed by the observer is formed on the liquidcrystal display panel 50 . To enable stereoscopic viewing, left-eye pixels L displaying left-eye images and right-eye pixels R displaying right-eye images are alternately arranged on the liquidcrystal display panel 50 . The pixels L for the left eye and the pixels R for the right eye can be obtained by taking images simultaneously with two cameras for the left eye and the right eye, for example, or can be calculated from one image data by logical operation. The two pixels obtained in this way include parallax information necessary for human beings to realize stereoscopic perception through binocular parallax.

在液晶显示面板50的前方配置了作为遮光隔板的视差隔板51。在视差隔板51上呈纵向条状而形成开口部51a...。开口部51a...的间隔对应于上述左眼用像素L和右眼用像素R的排列而设定。通过上述视差隔板51，将左眼用影像和右眼用影像左右分离，该被分离的影像分别入射到观察者的左眼2L、右眼2R中。这样观察者就能够观察到立体影像。In front of the liquidcrystal display panel 50, aparallax barrier 51 serving as a light-shielding barrier is arranged.Openings 51 a . . . are formed in theparallax barrier 51 in a longitudinal stripe shape. The intervals of theopenings 51a... are set corresponding to the arrangement of the left-eye pixel L and the right-eye pixel R described above. The left-eye video and the right-eye video are separated left and right by theparallax barrier 51 , and the separated video enters theleft eye 2L and theright eye 2R of the observer, respectively. In this way, the viewer can observe the stereoscopic image.

上述的液晶视差隔板方式的立体影像显示装置，例如在JP特开平3-119889号公报中被公开。利用图5对JP特开平3-119889号公报中所公开的过去的液晶视差隔板方式的立体影像显示装置的具体例子进行说明。The above-mentioned liquid crystal parallax barrier system stereoscopic image display device is disclosed in, for example, JP-A-3-119889. A specific example of a conventional liquid crystal parallax barrier method stereoscopic image display device disclosed in JP-A-3-119889 will be described with reference to FIG. 5 .

图5是具备配置在作为图像显示装置的液晶面板的前面配置的液晶视差隔板的视差隔板方式的立体影像显示装置10的概略横截面图。图5中，在背光12的表面上，通过第1偏振光片14而配置有排列了显示像素的透射型液晶面板16，而且还经由第2偏振光片18、玻璃隔离片20以及第3偏振光片22而配置有液晶视差隔板24，另外，在该液晶视差隔板24的表面上配置有第4偏振光片26。5 is a schematic cross-sectional view of a parallax barrier type stereoscopicimage display device 10 including a liquid crystal parallax barrier arranged in front of a liquid crystal panel as an image display device. In Fig. 5, on the surface of thebacklight 12, a transmissiveliquid crystal panel 16 in which display pixels are arranged is arranged through afirst polarizer 14, and asecond polarizer 18, aglass spacer 20 and a third polarizer are also arranged. A liquidcrystal parallax barrier 24 is disposed on thelight sheet 22 , and afourth polarizer 26 is disposed on the surface of the liquidcrystal parallax barrier 24 .

透射型液晶面板16包括：位于光的入射侧的背面玻璃板16a和位于光的射出侧的前面玻璃板16b；形成在背面玻璃板16a的内表面上的像素电极16c；形成在前面玻璃板16b的内表面上的彩色滤光片16d以及密封填充在背面玻璃板16a和前面玻璃板16b之间的液晶16e。透射型液晶面板16分别交替显示右眼用图像和左眼用图像。The transmissiveliquid crystal panel 16 includes: aback glass plate 16a positioned at the light incident side and afront glass plate 16b positioned at the light emitting side; apixel electrode 16c formed on the inner surface of theback glass plate 16a; apixel electrode 16c formed on thefront glass plate 16b Thecolor filter 16d on the inner surface of and theliquid crystal 16e sealed and filled between therear glass plate 16a and thefront glass plate 16b. The transmissiveliquid crystal panel 16 alternately displays images for the right eye and images for the left eye.

液晶视差隔板24在由在内侧分别形成有与透射型液晶面板16的像素L以及R的条纹平行的条状的电极及其对置电极(未图示)的2片玻璃板24a、24b所夹持的密闭空间中充填有液晶24c，在没有施加电压的状态下进行2D的影像显示，在施加了电压的状态下进行3D的影像显示。即，该液晶视差隔板24通过微机等控制装置来指定其XY地址，所以在3D显示的情况下能够在隔板表面上的任意位置形成任意形状的隔板条纹。The liquidcrystal parallax barrier 24 is composed of twoglass plates 24a and 24b on which strip-shaped electrodes parallel to the stripes of the pixels L and R of the transmissiveliquid crystal panel 16 and their counter electrodes (not shown) are respectively formed.Liquid crystal 24c is filled in the interposed airtight space, and 2D image display is performed in the state where no voltage is applied, and 3D image display is performed in the state where voltage is applied. That is, the XY addresses of the liquidcrystal parallax barrier 24 are specified by a control device such as a microcomputer, so that barrier stripes of arbitrary shapes can be formed at arbitrary positions on the barrier surface in the case of 3D display.

可是，产生纵条状的隔板条纹仅是显示3D影像的情况，在2D影像显示的情况下，就需要进行驱动控制使得停止隔板条纹的产生，由此在影像显示区域的整个范围内成为无色透明的状态。However, the generation of vertical spacer stripes is only a case of displaying 3D images, and in the case of 2D video display, it is necessary to perform drive control so as to stop the generation of spacer stripes, thereby becoming a 3D image in the entire range of the image display area. Colorless and transparent state.

在显示用的液晶面板16和液晶视差隔板24之间，配置了利用玻璃基板作为隔离片构件的玻璃隔离片20。显示用液晶面板和隔离片构件、以及隔离片构件和液晶视差隔板通过双面粘合胶带在它们的面板的周围边缘部粘合。Between theliquid crystal panel 16 for display and the liquidcrystal parallax barrier 24, theglass spacer 20 using a glass substrate as a spacer member is arrange|positioned. The liquid crystal panel for display and the spacer member, and the spacer member and the liquid crystal parallax barrier were bonded at peripheral edge portions of their panels with double-sided adhesive tapes.

该立体影像显示装置中，随着显示装置的画面向大型化方面发展而产生了要将显示用液晶面板16和液晶视差隔板24之间的间隔扩大的需要。即，在观察所显示的双眼视差图像时，为了观察到良好的立体影像，需要显示用液晶面板和液晶视差隔板之间的距离在一定的范围之内，在画面大型化而观察者和画面之间的距离也变大的情况下，产生了增大该距离的需要。也就是说，虽然对于在手机中使用的小型的屏幕来说该距离不怎么大，但是对于在T等中使用的屏幕来说该距离必然变大。In this stereoscopic image display device, as the size of the screen of the display device increases, there is a need to increase the distance between the displayliquid crystal panel 16 and the liquidcrystal parallax barrier 24 . That is, when observing a displayed binocular parallax image, in order to observe a good stereoscopic image, the distance between the display liquid crystal panel and the liquid crystal parallax barrier needs to be within a certain range. When the distance between them becomes large, there is a need to increase the distance. In other words, although the distance is not so large for a small screen used in a mobile phone, the distance must be large for a screen used in a T or the like.

作为调整显示用液晶面板和液晶视差隔板之间的间隔的手段，在上述JP特开平3-119889号公报中记载的立体影像显示装置中，在显示用液晶面板和液晶视差隔板之间配置了作为隔离片构件的玻璃基板或者丙烯板，可以通过该隔离片构件的厚度来调整显示用液晶面板和液晶视差隔板之间的间隔。之所以用玻璃基板和丙烯板来用作隔离片构件是因为其必须是能够透射来自背光的照明光的材料。As a means of adjusting the distance between the liquid crystal panel for display and the liquid crystal parallax barrier, in the stereoscopic image display device described in the above-mentioned Japanese Patent Application Laid-Open No. 3-119889, the liquid crystal panel for display and the liquid crystal parallax barrier are disposed between A glass substrate or an acrylic plate is used as the spacer member, and the distance between the display liquid crystal panel and the liquid crystal parallax barrier can be adjusted by the thickness of the spacer member. The reason why a glass substrate and an acrylic plate are used as a spacer member is that it must be a material capable of transmitting illumination light from a backlight.

发明的公开disclosure of invention

在上述这样的立体影像显示装置中，如果显示装置是小型的装置，则显示用液晶面板和液晶视差隔板之间的间隔较小即可，无需对隔离片构件进行过多的考虑，但是如果显示装置是大型装置，则有必要如前所述扩大显示用液晶面板和液晶视差隔板之间的间隔，比如，在40英寸的显示画面下需要5mm左右的间隔。由此，也需要考虑隔离片构件的透明度、构件成本。In the above-mentioned stereoscopic image display device, if the display device is a small device, the distance between the display liquid crystal panel and the liquid crystal parallax barrier is small, and there is no need to give too much consideration to the spacer member, but if If the display device is a large device, it is necessary to increase the distance between the display liquid crystal panel and the liquid crystal parallax barrier as described above. For example, a distance of about 5 mm is required for a 40-inch display screen. Therefore, it is also necessary to consider the transparency of the separator member and the member cost.

此外，由于在立体影像显示装置中使用的背光所产生的热，液晶视差隔板、隔离片构件、显示用液晶面板中使用的玻璃基板引起热膨胀，而且由于每个玻璃基板到背光的距离都不同，所以还存在由于各个玻璃基板膨胀率也不同而使玻璃基板产生变形的问题。立体影像显示装置由于是将液晶视差隔板、隔离片构件、显示用液晶面板、以及偏振光片等多段叠层而形成，如果基板由于热膨胀而产生变形，则还会对各个构件的表面的平坦性产生恶劣的影响，结果是造成立体影像显示装置的显示质量恶化。因此，如上述JP特开平3-119889号公报的立体影像显示装置那样，仅在显示用液晶面板和液晶视差隔板之间的隔离片构件上配置仅能透射光的构件，存在难于提供具有充分的显示质量的显示装置的问题。In addition, due to the heat generated by the backlight used in the stereoscopic image display device, the glass substrate used in the liquid crystal parallax barrier, the spacer member, and the display liquid crystal panel causes thermal expansion, and since the distance between each glass substrate and the backlight is different , so there is also the problem of deformation of the glass substrate due to the difference in expansion coefficient of each glass substrate. The three-dimensional image display device is formed by lamination of liquid crystal parallax barriers, spacer members, display liquid crystal panels, and polarizers. If the substrate is deformed due to thermal expansion, it will also affect the flatness of the surface of each member. Sexuality has a bad influence, and as a result, the display quality of the stereoscopic image display device is deteriorated. Therefore, as in the stereoscopic image display device of JP Patent Publication No. 3-119889, it is difficult to provide a member with sufficient light transmission only on the spacer member between the display liquid crystal panel and the liquid crystal parallax barrier. Problems with the display quality of the display device.

本申请发明人，为了解决这样的问题而反复进行各种研究的结果是发现了这样的情况：在利用液晶视差隔板方式的立体影像显示装置中，使构成显示用液晶面板的玻璃基板为无碱玻璃，而隔离片构件为与构成显示用液晶面板的玻璃基板不同的玻璃材料，由此能够解决上述问题，从而完成了本发明。As a result of repeated studies by the inventors of the present application in order to solve such problems, it has been found that in a three-dimensional image display device using a liquid crystal parallax barrier system, the glass substrate constituting the liquid crystal panel for display is made without glass substrates. Alkali glass, and the spacer member is made of a glass material different from the glass substrate constituting the display liquid crystal panel, whereby the above-mentioned problems can be solved, and the present invention has been completed.

即，本发明的目的在于提供一种立体影像显示装置及其制造方法，以解决上述问题为主题，尤其是也能够使用于液晶视差隔板方式的大型的立体影像显示装置中，显示质量良好，还考虑了背光产生的热导致的基板的热膨胀。That is, the object of the present invention is to provide a stereoscopic image display device and a manufacturing method thereof, which are aimed at solving the above-mentioned problems. In particular, it can be used in a large-scale stereoscopic image display device of a liquid crystal parallax barrier system, and the display quality is good. Thermal expansion of the substrate due to heat generated by the backlight is also considered.

本发明的上述目的可以通过下面的结构来实现。即，本发明的立体影像显示装置包括：背光、显示用液晶面板、液晶视差隔板、配置在上述显示用液晶面板和液晶视差隔板之间的隔离片构件，其特征在于，上述隔离片构件是由与构成上述显示用液晶面板的玻璃基板不同的玻璃材料构成的。The above objects of the present invention can be achieved by the following structures. That is, the stereoscopic image display device of the present invention includes: a backlight, a liquid crystal panel for display, a liquid crystal parallax barrier, and a spacer member disposed between the liquid crystal panel for display and the liquid crystal parallax barrier, wherein the spacer member It is made of a glass material different from the glass substrate constituting the above-mentioned display liquid crystal panel.

根据该结构，能够调整由于背光的发热导致的构成显示用液晶面板的由无碱玻璃构成的玻璃基板和隔离片构件的热膨胀所引起的变形。由此，作为隔离片构件，优选是与构成上述显示用液晶面板的玻璃基板相比热膨胀系数大的玻璃基板。According to this configuration, deformation due to thermal expansion of the glass substrate made of non-alkali glass and the spacer member constituting the display liquid crystal panel due to heat generated by the backlight can be adjusted. Therefore, as a spacer member, it is preferable that it is a glass substrate with a thermal expansion coefficient larger than the glass substrate which comprises the said liquid crystal panel for a display.

而且，在本发明的立体影像显示装置中，其特征在于，上述隔离片构件是钠玻璃，另外，构成显示用液晶面板的玻璃基板是无碱玻璃。通过将钠玻璃基板作为隔离片构件使用，与丙烯等材料相比，能够确保隔离片构件的透明程度，并且能够抑制成本的增加。此外，钠玻璃还具有不易变质变形、平面程度高等优点，所以能够提供一种具备不易伤害所叠层的其他构件、适于立体影像显示装置的隔离片构件的装置。Furthermore, in the stereoscopic image display device of the present invention, the spacer member is made of soda glass, and the glass substrate constituting the liquid crystal panel for display is made of alkali-free glass. By using the soda glass substrate as the spacer member, the degree of transparency of the spacer member can be ensured compared with materials such as acrylic, and an increase in cost can be suppressed. In addition, soda glass also has the advantages of not being easily deformed and deformed, and has a high degree of flatness, so it is possible to provide a device having a spacer member that is not likely to damage other laminated members and is suitable for a three-dimensional image display device.

而且，上述显示用液晶面板和隔离片构件的周围边缘部的整个周边、以及隔离片构件和液晶视差隔板的周围边缘部的整个周边由粘合剂粘结在一起，在上述显示用液晶面板和隔离片构件之间、以及隔离片构件和液晶视差隔板之间形成负压区域。在所述立体影像显示装置中，其特征在于，上述粘合剂涂敷在显示用液晶面板的显示区域以外的周围边缘部上。Moreover, the entire periphery of the peripheral edge portion of the above-mentioned display liquid crystal panel and the spacer member, and the entire periphery of the peripheral edge portion of the spacer member and the liquid crystal parallax barrier are bonded together by an adhesive, and the above-mentioned display liquid crystal panel Negative pressure regions are formed between the spacer member and the spacer member and the liquid crystal parallax barrier. In the above stereoscopic image display device, the adhesive is applied to peripheral edge portions other than the display area of the liquid crystal panel for display.

根据该结构，与过去的用双面粘合胶带进行的固定相比，能够实现更加稳固的固定，更加适于大型的立体影像显示装置。此外，由于使得隔离片构件和液晶视差隔板通过粘合剂而形成的区域、以及隔离片构件和显示用液晶面板通过粘合剂而形成的区域成为负压区域，能够使得各构件间的间隙稳定化，而且还能够抑制伴随着背光的发热的热膨胀导致的变形的产生。According to this structure, compared with conventional double-sided adhesive tape, more stable fixing can be realized, and it is more suitable for a large-sized three-dimensional image display device. In addition, since the region where the spacer member and the liquid crystal parallax barrier are formed with the adhesive, and the region where the spacer member and the liquid crystal panel for display are formed with the adhesive, become negative pressure regions, the gap between the members can be reduced. stabilized, and can also suppress the occurrence of deformation due to thermal expansion accompanying heat generation of the backlight.

更进一步，该粘合剂形成有一部分未涂敷的开口区域，同时在该开口区域涂敷有封固材料。Furthermore, the adhesive is formed with a part of the opening area not coated, and the sealing material is coated on the opening area.

根据该结构，与过去的用双面粘合胶带进行的固定相比，能够实现更加稳固的固定，更加适于大型的立体影像显示装置。此外，由于使得隔离片构件和液晶视差隔板通过粘合剂而形成的区域、以及隔离片构件和显示用液晶面板通过粘合剂而形成的区域成为负压区域，能够使得各构件之间的间隙稳定化，而且还能够抑制伴随着背光的发热的热膨胀导致的变形的产生。According to this structure, compared with conventional double-sided adhesive tape, more stable fixing can be realized, and it is more suitable for a large-sized three-dimensional image display device. In addition, since the area where the spacer member and the liquid crystal parallax barrier are formed by the adhesive, and the area where the spacer member and the liquid crystal panel for display are formed by the adhesive are negative pressure areas, the space between the members can be reduced. The gap is stabilized, and the occurrence of deformation due to thermal expansion accompanying heat generation of the backlight can be suppressed.

此外，本发明的立体影像显示装置的制造方法，其中该立体影像显示装置包括：显示用液晶面板；液晶视差隔板；配置在上述显示用液晶面板和液晶视差隔板之间的、由与构成上述显示用液晶面板的玻璃基板不同的玻璃材料等构成的隔离片构件，其特征在于，包括：在上述显示用液晶面板和隔离片构件的至少一方的周围边缘部、以及隔离片构件和液晶视差隔板的至少一方的周围边缘部上涂敷粘合剂，使得在该周围边缘部的至少一个位置上形成不存在粘合剂的开口区域的工序；通过该粘合剂将上述显示用液晶面板和隔离片构件、以及隔离片构件和液晶视差隔板粘合在一起，使该粘合剂硬化的工序；将上述显示用液晶面板和隔离片构件、以及隔离片构件和液晶视差隔板之间的空气从上述开口区域抽出的工序；密封上述开口区域的工序。该制造方法中，上述涂敷粘合剂的工序是在显示用液晶面板的显示区域以外的周围边缘部进行涂敷的工序。In addition, the method for manufacturing a stereoscopic image display device according to the present invention, wherein the stereoscopic image display device includes: a liquid crystal panel for display; a liquid crystal parallax barrier; The above-mentioned spacer member composed of glass materials different from the glass substrate of the liquid crystal panel for display is characterized in that it includes: a peripheral edge portion of at least one of the liquid crystal panel for display and the spacer member, and the spacer member and the liquid crystal parallax Coating an adhesive on at least one peripheral edge of the spacer so that an opening area without adhesive is formed at least one position of the peripheral edge; A process of adhering the spacer member, the spacer member and the liquid crystal parallax barrier together, and curing the adhesive; placing the liquid crystal panel for display above and the spacer member, and the spacer member and the liquid crystal parallax barrier The process of extracting the air from the above-mentioned opening area; the process of sealing the above-mentioned opening area. In this manufacturing method, the step of applying the adhesive is a step of applying the adhesive to a peripheral edge portion other than the display area of the liquid crystal panel for display.

根据该制造方法，与过去的张贴双面粘合胶带的作业相比，由于以涂敷粘合剂的作业而完成，所以制造变得容易，不产生气泡而能够实现更加稳固的固定。而且，由于能够使隔离片构件和液晶视差隔板通过粘合剂而形成的区域、以及隔离片构件和显示用液晶面板通过粘合剂而形成的区域成为负压区域，能够使得各构件之间的间隙稳定化，而且还能够抑制伴随着背光的发热的热膨胀导致的变形的产生。According to this manufacturing method, compared with pasting the double-sided adhesive tape in the past, it is completed by applying the adhesive, so the manufacturing becomes easier, and more stable fixation can be realized without generating air bubbles. In addition, since the area where the spacer member and the liquid crystal parallax barrier are formed by the adhesive, and the area where the spacer member and the liquid crystal panel for display are formed by the adhesive can be negative pressure areas, it is possible to make the space between the members The gap is stabilized, and it is also possible to suppress the occurrence of deformation caused by thermal expansion accompanying heat generation of the backlight.

实施发明的最佳方式The best way to practice the invention

下面参照附图对本发明的立体影像显示装置的实施形式进行详细的说明。图1是表示本发明的立体影像显示装置30的结构的图，(a)是概略横截面图，(b)是其A部分的放大图。本发明的立体影像显示装置30，在背光32的上部上配置有隔着玻璃基板等的隔离片构件40而通过粘合剂粘合的显示用液晶面板36和液晶视差隔板44而构成。Embodiments of the stereoscopic image display device of the present invention will be described in detail below with reference to the accompanying drawings. 1 is a diagram showing the structure of a stereoscopicimage display device 30 according to the present invention, (a) is a schematic cross-sectional view, and (b) is an enlarged view of part A thereof. The stereoscopicimage display device 30 of the present invention is configured by arranging a displayliquid crystal panel 36 and a liquidcrystal parallax barrier 44 bonded with an adhesive on top of abacklight 32 via aspacer member 40 such as a glass substrate.

显示用液晶面板36是透射型液晶面板，包括：位于光的入射侧的背面玻璃板36a和位于光的射出侧的前面玻璃板36b；形成在背面玻璃板36a的内表面上的未图示的像素电极；形成在前面玻璃板36b的内表面上的未图示的彩色滤光片；以及用密封材料密封填充在背面玻璃板36a和前面玻璃板36b之间的液晶36e。在显示用液晶面板36上，在进行立体显示时分别交替显示右眼用图像和左眼用图像，在不进行立体显示时显示通常的图像。The displayliquid crystal panel 36 is a transmissive liquid crystal panel, including: a back glass plate 36a positioned at the incident side of light and a front glass plate 36b positioned at the light emitting side; A pixel electrode; an unshown color filter formed on the inner surface of the front glass plate 36b; and a liquid crystal 36e filled between the back glass plate 36a and the front glass plate 36b are hermetically sealed with a sealing material. On theliquid crystal panel 36 for display, an image for the right eye and an image for the left eye are alternately displayed when stereoscopic display is performed, and a normal image is displayed when stereoscopic display is not performed.

液晶视差隔板44虽然是在通常的液晶显示装置中所使用的那样的单纯的矩阵驱动型的视差隔板和利用有源矩阵驱动型的液晶面板的视差隔板也没有问题，但是由于需要在基板上形成复杂的配线等，很有可能因此而导致良品率下降。Although the liquidcrystal parallax barrier 44 is a simple matrix-driven parallax barrier as used in a common liquid crystal display device or a parallax barrier using an active matrix-driven liquid crystal panel, there is no problem, but due to the need for Complicated wiring etc. are formed on the substrate, which may lead to a decrease in the yield rate.

因此，液晶视差隔板44，在夹持液晶44c的一对透明的玻璃基板44a、44b中，在一个玻璃基板44a上整体形成ITO等的透明电极，而在另一个玻璃基板44b上，在除了作为透射部的部位之外的地方形成透明电极。且在电极上没有施加驱动电压时，按完全透射光这样的取向设定液晶。这样，通过施加驱动电压，使得两个基板上形成透明电极的位置成为遮光部，仅在一个基板上没有形成透明电极的部分成为使光透射的透射部。Therefore, in the liquidcrystal parallax barrier 44, among the pair oftransparent glass substrates 44a and 44b sandwiching the liquid crystal 44c, a transparent electrode such as ITO is integrally formed on oneglass substrate 44a, and a transparent electrode such as ITO is formed on the other glass substrate 44b except A transparent electrode is formed in a place other than the portion serving as the transmissive portion. And when no driving voltage is applied to the electrodes, the liquid crystal is set in such an orientation that it completely transmits light. In this way, by applying a driving voltage, the positions where the transparent electrodes are formed on the two substrates become the light-shielding portions, and only the portion where the transparent electrodes are not formed on one substrate becomes the transmissive portion that transmits light.

这样的液晶视差隔板44仅在要形成透射部的位置上不形成透明电极即可，与使用有源矩阵驱动型等的液晶面板的隔板相比，能够以比较简单的工艺进行制造。而且，通过改变透明电极的未形成部的形状等，能够比较自由地使透射部的形状和位置变化。Such a liquidcrystal parallax barrier 44 does not need to form a transparent electrode only at a position where a transmissive portion is to be formed, and can be manufactured with a relatively simple process compared with a barrier using a liquid crystal panel of an active matrix drive type or the like. Furthermore, by changing the shape of the unformed portion of the transparent electrode, etc., the shape and position of the transmissive portion can be relatively freely changed.

背光32是为了实现高亮度而使用了多个冷阴极管的正下方型的背光。尤其对于需要隔离片构件40的立体影像显示装置来说，显示装置是大型装置，因为通常中小型的液晶显示装置中使用的所谓侧面光源型的背光的亮度不够，所以使用正下方型的背光。另外，视差隔板方式的情况下，即使在2D显示的情况下具有足够的亮度，但是在切换到立体显示时由于隔板的遮光，因此而使得亮度不足，所以需要使用能够实现高亮度的正下方型背光。且背光32、显示用液晶面板36、隔离片构件40、液晶视差隔板44等的构成构件用粘合材料或者粘合胶带等固定，并以框体保持其侧面、背面，而容纳在适当的壳体内。而且，在上述现有技术那样的立体影像显示装置中，一般显示用液晶面板和隔离片构件、以及隔离片构件和液晶视差隔板用双面粘合胶带将它们的面板周围边缘部粘合。由此，在显示装置的画面大型化的情况下，用双面粘合胶带进行的粘合方法中具有强度不够的问题。Thebacklight 32 is a direct type backlight using a plurality of cold-cathode tubes in order to achieve high brightness. Especially for a three-dimensional image display device that requires thespacer member 40, the display device is a large device, and since the so-called side light type backlight used in small and medium-sized liquid crystal display devices generally has insufficient brightness, a direct type backlight is used. In addition, in the case of the parallax barrier method, even if it has sufficient brightness in the case of 2D display, when switching to stereoscopic display, the brightness is insufficient due to the light shielding of the barrier, so it is necessary to use a positive display that can achieve high brightness. Downside type backlight. And thebacklight 32, the displayliquid crystal panel 36, thespacer member 40, the liquidcrystal parallax barrier 44 and other constituent members are fixed with an adhesive material or an adhesive tape, and the side and the back are held by the frame, and housed in an appropriate place. inside the shell. In addition, in the stereoscopic image display device of the above-mentioned prior art, generally, the display liquid crystal panel and the spacer member, and the spacer member and the liquid crystal parallax barrier are bonded to their peripheral edge portions with a double-sided adhesive tape. Therefore, when the size of the screen of the display device is increased, there is a problem of insufficient strength in the bonding method using the double-sided adhesive tape.

另外，在粘合胶带与各构件之间不产生气泡，将大型的显示用液晶面板、液晶视差隔板与玻璃隔离片等的隔离片构件的整个面用双面粘合胶带粘结的作业是非常困难的。而且如果产生了气泡则会对显示造成影响。因此，显示用液晶面板与隔离片构件、以及隔离片构件与液晶视差隔板通过后述的方法来固定。In addition, the operation of bonding the entire surface of spacer members such as large liquid crystal panels for display, liquid crystal parallax barriers, and glass spacers with double-sided adhesive tape is very difficult. And if bubbles are generated, it will affect the display. Therefore, the display liquid crystal panel and the spacer member, and the spacer member and the liquid crystal parallax barrier are fixed by a method described later.

构成显示用液晶面板36的背面玻璃板36a以及前面玻璃板36b除了要求透明性能良好、不易变质、变形、且平面程度高之外，由于还需要形成TFT驱动元件、像素电极、对置电极、彩色滤光片等，所以还需要有耐化学腐蚀性，由于从玻璃中溶出碱影响到TFT性能，所以使用无碱的玻璃材料。构成液晶视差隔板44的玻璃板44a、44b也是一样。为了避免液晶面板中使用的无碱玻璃由于电极和TFT制膜时的热引起变形，需要在其材料和制造方法上下功夫以减小热膨胀系数，由此也导致其成本很高。The back glass plate 36a and the front glass plate 36b constituting the displayliquid crystal panel 36 are not only required to have good transparency, not easy to deteriorate, deform, and have a high degree of flatness, but also need to form TFT drive elements, pixel electrodes, opposite electrodes, and color elements. Filters, etc., so chemical corrosion resistance is also required. Since the dissolution of alkali from the glass affects the performance of the TFT, an alkali-free glass material is used. The same applies to theglass plates 44 a and 44 b constituting the liquidcrystal parallax barrier 44 . In order to avoid the deformation of the alkali-free glass used in the liquid crystal panel due to the heat of electrodes and TFT film formation, it is necessary to work hard on its materials and manufacturing methods to reduce the thermal expansion coefficient, which also leads to high costs.

另一方面，配置在显示用液晶面板36和液晶视差隔板44之间的隔离片构件40，如果显示装置是大型的话，需要如上所述增大显示用液晶面板和液晶视差隔板的间隔，例如，40英寸的显示画面下就需要5mm左右的间隔。由此、就需要考虑隔离片构件的透明度、部件成本。On the other hand, thespacer member 40 disposed between theliquid crystal panel 36 for display and the liquidcrystal parallax barrier 44 needs to increase the distance between the liquid crystal panel for display and the liquid crystal parallax barrier as described above if the display device is large. For example, a 40-inch display requires a spacing of about 5 mm. Therefore, it is necessary to consider the transparency of the spacer member and the cost of parts.

此外，还需要考虑立体影像显示装置30中使用的背光32导致的热的影响。尤其是在背光32是使用了多个冷阴极管的正下方型的情况下，发热导致的影响是非常高的。而且，由于显示用液晶面板36和液晶视差隔板44分别使用了2个基板，各自的基板表面就有4个，且隔离片构件40也有2个基板表面。立体影像显示装置30是将它们叠层而构成，至少存在10个基板表面。因此，由于各构件的表面的平坦性和制造中途产生的损伤使得产生了牛顿环或莫尔条纹等，会给装置的显示品质造成很大影响。In addition, the influence of heat caused by thebacklight 32 used in the stereoscopicimage display device 30 also needs to be considered. In particular, when thebacklight 32 is a direct type using a plurality of cold-cathode tubes, the influence of heat generation is very high. Furthermore, since the displayliquid crystal panel 36 and the liquidcrystal parallax barrier 44 each use two substrates, each has four substrate surfaces, and thespacer member 40 also has two substrate surfaces. The three-dimensionalimage display device 30 is formed by laminating them, and there are at least 10 substrate surfaces. Therefore, Newton's rings, moiré fringes, and the like are generated due to the flatness of the surface of each member and damage generated in the middle of manufacturing, which greatly affects the display quality of the device.

在本发明的立体影像显示装置30中，从上述观点出发，相对于用无碱玻璃构成显示用液晶面板36和液晶视差隔板44的玻璃板36a、36b、44a、44b，隔离片构件40用与构成显示用液晶面板以及液晶视差隔板的无碱玻璃不同的玻璃材料构成。In the stereoscopicimage display device 30 of the present invention, from the above viewpoint, theglass plates 36a, 36b, 44a, 44b of theliquid crystal panel 36 for display and the liquidcrystal parallax barrier 44 are made of non-alkali glass, and thespacer member 40 It is made of a different glass material than the alkali-free glass that makes up the liquid crystal panel for display and the liquid crystal parallax barrier.

作为隔离片构件40的玻璃材料，优选例如使用相对于无碱玻璃的玻璃板36a、36b、44a、44b而言热膨胀系数大的玻璃材料。这是因为，显示用液晶面板36配置在背光32的正上方，隔离片构件40配置在显示用液晶面板36的上面，所以背光32的发热导致的影响对构成显示用液晶面板36的玻璃基板36a、36b的作用比对隔离片构件40的作用大。As the glass material of thespacer member 40, for example, a glass material having a large thermal expansion coefficient with respect to theglass plates 36a, 36b, 44a, and 44b of alkali-free glass is preferably used. This is because theliquid crystal panel 36 for display is arranged directly above thebacklight 32, and thespacer member 40 is arranged on the upper surface of theliquid crystal panel 36 for display, so the influence caused by the heat generated by thebacklight 32 affects the glass substrate 36a constituting theliquid crystal panel 36 for display. The effect of , 36b is greater than the effect on thespacer member 40 .

图2是表示背光32的发热导致的热应力的示意图，(a)是表示热应力的方向的图，(b)是示意性表示热膨胀导致的面板的变形的图。如图2所示，在隔离片构件40和玻璃基板36a、36b为同样的玻璃材料的情况下，与隔离片构件40的热膨胀相比，玻璃基板36a、36b的热膨胀大，所以在隔离片构件40和玻璃基板36b的接合部(用粘合剂等形成的固接部)产生变形，造成显示质量降低。2 is a schematic diagram showing thermal stress due to heat generation of thebacklight 32, (a) is a diagram showing the direction of thermal stress, and (b) is a diagram schematically showing deformation of the panel due to thermal expansion. As shown in FIG. 2, when thespacer member 40 and the glass substrates 36a and 36b are made of the same glass material, the thermal expansion of the glass substrates 36a and 36b is larger than the thermal expansion of thespacer member 40. 40 and the glass substrate 36b (a fixed portion formed with an adhesive or the like) is deformed, resulting in a decrease in display quality.

如本申请那样作为隔离片构件40，通过采用具有比如上所述那样的构成显示用液晶面板36的玻璃基板36a、36b的热膨胀系数大的热膨胀系数的玻璃材料，从而能够降低背光32的热造成的影响。也就是说，由于接近背光32的显示用液晶面板36膨胀的大小和与显示用液晶面板36相比远离背光32的隔离片构件40膨胀的大小之间的差异减小了，所以也就减小了隔离片构件40和玻璃基板36b的接合部的变形。As in the present application, as thespacer member 40, by using a glass material having a thermal expansion coefficient larger than that of the glass substrates 36a, 36b constituting the displayliquid crystal panel 36 as described above, the heat caused by thebacklight 32 can be reduced. Impact. That is, since the difference between the expansion size of the displayliquid crystal panel 36 close to thebacklight 32 and the expansion size of thespacer member 40 away from thebacklight 32 compared with the displayliquid crystal panel 36 is reduced, it is also reduced. The deformation of the joint portion of thespacer member 40 and the glass substrate 36b is prevented.

作为与玻璃基板36a、36b中使用的无碱玻璃相比热膨胀系数大的玻璃材料，例如可以使用钠玻璃。钠玻璃的热膨胀系数通常是85×10^-7/℃～95×10^-7/℃(0～300℃)左右，与无碱玻璃的热膨胀系数30×10^-7/℃～50×10^-7/℃(0～300℃)相比非常大。而且，钠玻璃还具有价格低廉，透明度也很好，不易受热变质，平坦性优秀，不易损伤等优点，能够作为适于立体影像显示装置的隔离片构件。Soda glass can be used as a glass material with a thermal expansion coefficient larger than the alkali-free glass used for glass substrate 36a, 36b, for example. The thermal expansion coefficient of soda glass is usually about 85×10^-7 /℃～95×10^-7 /℃ (0～300℃), and the thermal expansion coefficient of alkali-free glass is 30×10^-7 /℃～50×10^-7 /°C (0 to 300°C) is very large. Moreover, the soda glass also has the advantages of low price, good transparency, less heat deterioration, excellent flatness, and less damage, and can be used as a spacer member suitable for a stereoscopic image display device.

而且，作为玻璃基板36a、36b所使用的玻璃除了无碱玻璃之外，还可以使用热膨胀系数为30×10^-7/℃(0～300℃)左右的硼硅酸类玻璃。Furthermore, borosilicate glass having a thermal expansion coefficient of about 30×10⁻⁷ /°C (0 to 300° C.) may be used as the glass used for the glass substrates 36 a and 36 b in addition to non-alkali glass.

图3是表示图1所示的立体影像显示装置30的基板接合部的截断平面的示意图。在隔离片构件40中，显示用液晶面板的显示区域之外的周围边缘部涂敷有热硬化性或者紫外线硬化性的粘合剂48a(48b)，用该粘合剂48a(48b)粘结显示用液晶面板36(液晶视差隔板44)。作为粘合剂48a(48b)，比较适当的是机械性粘结强度高、对温度、湿度的环境变化的稳定性好、能够利用现有设备进行涂敷的热硬化性或者紫外线硬化性的密封材料。而且，粘合剂48a(48b)上，在周围边缘部的一部分上形成有没有涂敷粘合剂的开口区域50。FIG. 3 is a schematic diagram illustrating a sectional plane of a substrate bonding portion of the stereoscopicimage display device 30 shown in FIG. 1 . In thespacer member 40, a thermosetting or ultravioletcurable adhesive 48a (48b) is applied to the periphery of the liquid crystal panel for display outside the display area, and the adhesive 48a (48b) is used for bonding. Display liquid crystal panel 36 (liquid crystal parallax barrier 44 ). As the adhesive 48a (48b), a thermosetting or ultraviolet curable sealant that has high mechanical bonding strength, good stability against environmental changes in temperature and humidity, and can be applied with existing equipment is suitable. Material. Furthermore, in the adhesive 48a (48b), anopening area 50 where no adhesive is applied is formed in a part of the peripheral edge.

粘结工序如下所述进行。首先，在隔离片构件40的显示用液晶面板的显示区域之外的周围边缘部，涂敷由热硬化性或者紫外线硬化性的密封材料构成的粘合剂48a(48b)。在粘合剂48a(48b)的涂敷中，进行作业，使得在周围边缘部的一部分上形成没有涂敷粘合剂48a(48b)的开口区域50。The bonding process was performed as follows. First, an adhesive 48 a ( 48 b ) made of a thermosetting or ultraviolet curable sealing material is applied to the periphery of thespacer member 40 outside the display area of the liquid crystal panel for display. In the application of the adhesive 48a (48b), work is performed so that theopening area 50 where the adhesive 48a (48b) is not applied is formed in a part of the peripheral edge.

接着，粘合隔离片构件40和显示用液晶面板36(液晶视差隔板44)，使粘合剂48a(48b)硬化。在粘合剂48a(48b)硬化之后，从开口区域50，抽取出隔离片构件40和显示用液晶面板36(液晶视差隔板44)之间用粘合剂48a(48b)造成的空间中的空气。最后用封固材料密封开口区域50，使隔离片构件40和显示用液晶面板36(液晶视差隔板44)之间用粘合剂48a(48b)造成的区域内保持负压。而且对于封固材料，只要是能可靠的密封开口区域50的材料即可，紫外线硬化树脂、丙烯树脂或者单液性或两液性的环氧树脂等，从机械性粘结强度、对温度、湿度的环境变化的稳定性、或者能够利用现有设备进行涂敷等方面来看都很适合。如此的抽取出空气的话，能够防止使用立体影像显示装置30时由于背光产生的热使得空气膨胀。而且在抽取空气时不一定要完全的抽取所有的空气，只要大概在80kPa以下就行，优选在50kPa以下。另外，在粘结如上述那样的显示用液晶面板和隔离片构件、以及隔离片构件和液晶视差隔板的情况下，在显示用液晶面板和隔离片构件之间、以及隔离片构件和液晶视差隔板之间分布有球状的隔离件，在保证各构件之间的距离的均匀性方面是很有效果的。Next, thespacer member 40 and the display liquid crystal panel 36 (liquid crystal parallax barrier 44 ) are bonded together, and the adhesive 48 a ( 48 b ) is cured. After the adhesive 48a (48b) is cured, from theopening area 50, the space formed by the adhesive 48a (48b) between thespacer member 40 and the display liquid crystal panel 36 (liquid crystal parallax barrier 44) is extracted. Air. Finally, theopening area 50 is sealed with a sealing material, and negative pressure is maintained in the area formed by the adhesive 48a (48b) between thespacer member 40 and the display liquid crystal panel 36 (liquid crystal parallax barrier 44). And for the sealing material, as long as it is a material that can reliably seal theopening area 50, ultraviolet curable resin, acrylic resin, or one-component or two-component epoxy resin, etc., can be used in terms of mechanical bonding strength, temperature, It is suitable in terms of stability against environmental changes in humidity, or the ability to apply using existing equipment. By extracting the air in this way, it is possible to prevent the air from expanding due to the heat generated by the backlight when the stereoscopicimage display device 30 is used. And when extracting air, it is not necessary to extract all the air completely, as long as it is below 80kPa, preferably below 50kPa. In addition, when bonding the above-mentioned liquid crystal panel for display and the spacer member, and the spacer member and the liquid crystal parallax barrier, between the liquid crystal panel for display and the spacer member, and between the spacer member and the liquid crystal parallax barrier Spherical spacers are distributed between the partitions, which is very effective in ensuring the uniformity of the distance between the components.

如上所述，根据本发明的立体影像显示装置，能够调整由于背光的发热导致的构成显示用液晶面板的玻璃基板和隔离片构件之间的热膨胀引起的变形。作为隔离片构件，采用与构成显示用液晶面板的玻璃基板相比热膨胀系数大的玻璃基板，尤其通过使用钠玻璃，与丙烯等材料相比，还能够确保隔离片构件的透明度，抑制成本的增加。As described above, according to the stereoscopic image display device of the present invention, deformation due to thermal expansion between the glass substrate constituting the display liquid crystal panel and the spacer member due to heat generated by the backlight can be adjusted. As the spacer member, use a glass substrate with a higher thermal expansion coefficient than the glass substrate constituting the display liquid crystal panel. In particular, by using soda glass, the transparency of the spacer member can be ensured compared with acrylic and other materials, and the increase in cost can be suppressed. .

此外，钠玻璃具有不易变质、平面度高、难于损伤等优点，所以能够提供一种具备适于立体影像显示装置的隔离片构件的装置。In addition, soda glass has advantages such as less deterioration, high flatness, and less damage, so it is possible to provide a device including a spacer member suitable for a stereoscopic image display device.

此外，由于隔离片构件40和液晶视差隔板44、以及隔离片构件40和显示用液晶面板36是通过粘合剂48b、48a来粘结的，与象过去那样粘贴双面粘合胶带的作业相比，通过涂敷粘合剂48a、48b的作业就可实现，所以制造加工容易，同时还能实现更加稳固的固定。而且，隔离片构件40和液晶视差隔板44之间通过粘合剂48b形成的区域、以及隔离片构件40和显示用液晶面板36之间通过粘合剂48a形成的区域由于构成负压区域，能够使各构件之间的间隙稳定化，从而能够抑制伴随着背光32的发热而产生的热膨胀导致的基板的变形的发生。In addition, since thespacer member 40 and the liquidcrystal parallax barrier 44, and thespacer member 40 and the displayliquid crystal panel 36 are bonded by theadhesives 48b, 48a, it is different from the work of pasting the double-sided adhesive tape as in the past. Compared with this, it can be realized by applying the adhesive 48a, 48b, so the manufacturing process is easy, and at the same time, more stable fixing can be realized. Furthermore, since the area formed by the adhesive 48b between thespacer member 40 and the liquidcrystal parallax barrier 44 and the area formed by the adhesive 48a between thespacer member 40 and theliquid crystal panel 36 for display constitute a negative pressure area, The gap between the members can be stabilized, and the occurrence of deformation of the substrate due to thermal expansion accompanying heat generation of thebacklight 32 can be suppressed.
