输送装置19具有：辊保持部19a(放卷部)，其对第三卷材R3进行保持，且从该第三卷材R3沿着第三光学构件片体F3S的长度方向放卷第三光学构件片体F3S；单个或多个(在图中仅示出一个)引导辊19b，其为了沿着规定的片材输送路径将从第三卷材R3放卷的第三光学构件片体F3S引导至第三贴合装置18的贴合位置而绕卷第三光学构件片体F3S的隔片SS侧；切割装置19c(切割部)，其对片材输送路径上的第三光学构件片体F3S实施残留了隔片SS的半切割；刀口19d，其将实施了半切割的第三光学构件片体F3S的隔片SS侧卷挂成锐角，一边使第三光学构件F13从隔片SS分离，一边将第三光学构件F13供给至贴合位置；以及隔片回收部19e，其卷取经过刀口19d而变成单独的隔片SS。Theconveyance device 19 has aroller holding part 19a (unwinding part) that holds the third roll R3 and unwinds the third optical member sheet F3S from the third roll R3 along the longitudinal direction of the third optical member sheet F3S. member sheet F3S; single or multiple (only one is shown in the figure)guide roller 19b for guiding the third optical member sheet F3S unwound from the third roll R3 along a prescribed sheet conveyance path To the bonding position of thethird bonding device 18, the separator SS side of the third optical member sheet F3S is wound; thecutting device 19c (cutting part) for the third optical member sheet F3S on the sheet conveyance path The half-cut with the spacer SS remaining is performed; theknife edge 19d winds the side of the spacer SS of the third optical member sheet F3S subjected to the half-cut at an acute angle, while separating the third optical member F13 from the spacer SS, While supplying the 3rd optical member F13 to the bonding position; and the spacer collection|recovery part 19e, it winds up and becomes an independent spacer SS through theknife edge 19d.

位于输送装置19的起点的辊保持部19a和位于输送装置19的终点的隔片回收部19e例如相互同步地驱动。由此，在辊保持部19a向第三光学构件片体F3S的输送方向放卷第三光学构件片体F3S的同时，隔片回收部19e卷取经由刀口19d而成为单独的隔片SS。Theroller holding unit 19a located at the starting point of the conveyingdevice 19 and theseparator collecting unit 19e located at the end point of the conveyingdevice 19 are driven synchronously with each other, for example. Thereby, the spacer collection|recovery part 19e winds up the spacer SS which became independent via theknife edge 19d, simultaneously with the roller holding|maintenance part 19a unwinding the 3rd optical member sheet|seat F3S to the conveyance direction of the 3rd optical member sheet|seat F3S.

在第三光学构件片体F3S被放卷规定长度之时，切割装置19c跨越与第三光学构件片体F3S的长度方向(放卷方向)正交的宽度方向的全宽残留隔片SS地对第三光学构件片体F3S进行切割(即仅切断第三光学构件片F3)。切割装置19c调整切割刀具的进退位置，以使得隔片SS不会由于在第三光学构件片体F3S的输送中作用的张力而破裂。When the third optical member sheet F3S is unwound to a predetermined length, thecutting device 19c faces the remaining spacer SS across the full width of the width direction (unwinding direction) orthogonal to the longitudinal direction (unwinding direction) of the third optical member sheet F3S. The 3rd optical member sheet|seat F3S is cut|disconnected (that is, only the 3rd optical member sheet|seat F3 is cut|disconnected). Thecutting device 19c adjusts the advancing and retreating position of the cutting blade so that the spacer SS is not broken by the tension acting during the conveyance of the third optical member sheet F3S.

在所述切割后的第三光学构件片体F3S上，形成有跨越第三光学构件片体F3S的宽度方向的全宽的切割线。On the 3rd optical member sheet|seat F3S after the said cut|disconnection, the cutting line which spans the full width of the width direction of the 3rd optical member sheet|seat F3S is formed.

在此，在刀口19d的顶端部附近、即第三贴合装置18的贴合位置附近的面板输送上游侧的部位，设置有对该部位的第三光学构件F13的放卷方向下游侧的切割端进行检测的第一检测照相机22。第一检测照相机22的检测信息被发送给控制装置20。控制装置20例如在第一检测照相机22检测到第三光学构件F13的下游侧端的时刻使输送装置19暂时停止。其后，在第一检测照相机22检测到第二单面贴合面板P12的下游侧端的时刻，控制装置20使输送装置19驱动，使第二单面贴合面板P12和第三光学构件F13同步并能够将它们导入至第三贴合装置18的贴合位置。Here, near the front end of theknife edge 19d, that is, near the bonding position of thethird bonding device 18, on the upstream side of the panel conveyance, a cut is provided on the downstream side of the third optical member F13 in the unwinding direction. Thefirst detection camera 22 for detection. The detection information of thefirst detection camera 22 is sent to thecontrol device 20 . Thecontrol device 20 temporarily stops thetransport device 19 when thefirst detection camera 22 detects the downstream side end of the third optical member F13, for example. Thereafter, when thefirst detection camera 22 detects the downstream side end of the second single-sided bonding panel P12, thecontrol device 20 drives the conveyingdevice 19 to synchronize the second single-sided bonding panel P12 and the third optical member F13. And they can be introduced into the bonding position of the3rd bonding apparatus 18.

另一方面，在第一检测照相机22的放卷方向上游侧、即相比切割装置19c位于一个第三光学构件F13程度的所述放卷方向下游侧的部位，同样设置有对第三光学构件F13的放卷方向下游侧的切割端进行检测的第二检测照相机23(检测部)。第二检测照相机23的检测信息也被发送给控制装置20。控制装置20例如在通过切割装置19c进行了第三光学构件片F3的切割后将其放卷，在第二检测照相机23检测到该切割端(第三光学构件片F3的最上游侧的切割线)的时刻，使输送装置19暂时停止。此时，采用切割装置19c进行第三光学构件片F3的切割。即、沿着第二检测照相机23的检测位置(相当于第三光学构件片F3上的第二检测照相机23的光轴延长位置)与切割装置19c的切割位置(相当于第三光学构件片F3上的切割装置19c的切割刀具进退位置)之间的片材输送路径的距离相当于第三光学构件F13的长度。On the other hand, on the upstream side of the unwinding direction of thefirst detection camera 22, that is, at a portion located on the downstream side of the unwinding direction by one third optical member F13 relative to thecutting device 19c, a pair of third optical members is also provided. The 2nd detection camera 23 (detection part) which detects the cutting edge of the downstream side of the unwinding direction of F13. The detection information of thesecond detection camera 23 is also sent to thecontrol device 20 . For example, thecontrol device 20 unwinds the third optical member sheet F3 after cutting it by thecutting device 19c, and thesecond detection camera 23 detects the cut end (cutting line on the most upstream side of the third optical member sheet F3). ) moment, the conveyingdevice 19 is temporarily stopped. At this time, cutting of the 3rd optical member sheet|seat F3 is performed using thecutting apparatus 19c. That is, along the detection position of the second detection camera 23 (corresponding to the optical axis extension position of thesecond detection camera 23 on the third optical member sheet F3) and the cutting position of thecutting device 19c (corresponding to the third optical member sheet F3 The distance of the sheet conveying path between the cutting blade advancing and retreating positions of thecutting device 19c on the upper surface corresponds to the length of the third optical member F13.

例如在切割出贴合于同一尺寸的液晶面板P的第三光学构件F13的情况下，在第三光学构件片体F3S的长度方向上等间隔地形成所述切割线。第三光学构件片F3通过多个切割线在长度方向上被划分为多个区域，该第三光学构件片F3上的由在长度方向相邻的一对切割线夹着的区域分别被做成第三光学构件F13。第三光学构件F13的长度在本实施方式中被设定为在显示区域P4的全长以上且在液晶面板P的全长以下。For example, when cutting out the 3rd optical member F13 bonded to the liquid crystal panel P of the same size, the said cutting line is formed at equal intervals in the longitudinal direction of the 3rd optical member sheet|seat F3S. The third optical member sheet F3 is divided into a plurality of regions in the longitudinal direction by a plurality of cutting lines, and the regions sandwiched by a pair of cutting lines adjacent in the longitudinal direction on the third optical member sheet F3 are respectively made into The third optical member F13. The length of the 3rd optical member F13 is set so that it may be more than the full length of the display area P4 and below the full length of liquid crystal panel P in this embodiment.

又，切割装置19c被设定为能够沿着第三光学构件片体F3S的片材输送路径移动。通过该移动，沿着第二检测照相机23的检测位置与切割装置19c的切割位置之间的片材输送路径的距离发生变动。切割装置19c的移动通过控制装置20控制，例如在采用切割装置19c进行第三光学构件片F3的切割之后将第三光学构件片F3放卷了一个第三光学构件F13程度的距离时，其切割端偏离规定位置的情况下，通过切割装置19c的移动来修正该偏差。Moreover, thecutting device 19c is set so that it can move along the sheet|seat conveyance path of the 3rd optical member sheet|seat F3S. This movement changes the distance along the sheet conveyance path between the detection position of thesecond detection camera 23 and the cutting position of thecutting device 19c. The movement of thecutting device 19c is controlled by thecontrol device 20. For example, after the third optical member sheet F3 is cut by thecutting device 19c, the third optical member sheet F3 is unwound by a distance of a third optical member F13. When the end deviates from a predetermined position, the deviation is corrected by moving thecutting device 19c.

另外，也能够通过切割装置19c的移动来对应长度不同的第三光学构件F13的切割。又，也可以做成通过使切割装置19c以及第二检测照相机23的至少一方在片材输送方向移动，来进行所述修正或第三光学构件F13的长度变更的结构。又，切割装置19c和第二检测照相机23相互接近，但为了防止伴随着切割装置19c的移动等的第二检测照相机23的振动，切割装置19c和第二检测照相机23分别由另外的框架来支承比较理想。Moreover, the cutting of the 3rd optical member F13 from which length differs can also be corresponded by the movement of thecutting apparatus 19c. In addition, the correction or the length change of the third optical member F13 may be performed by moving at least one of thecutting device 19c and thesecond detection camera 23 in the sheet conveyance direction. Also, thecutting device 19c and thesecond detection camera 23 are close to each other, but in order to prevent vibration of thesecond detection camera 23 accompanying the movement of thecutting device 19c, thecutting device 19c and thesecond detection camera 23 are supported by separate frames respectively. ideal.

刀口19d被配置在辊式输送机5的下方，并在第三光学构件片体F3S的宽度方向上至少沿着第三光学构件片体F3S的全宽延伸。刀口19d将第三光学构件片体F3S卷挂成锐角，以便与半切割后的第三光学构件片体F3S的隔片SS侧滑动接触。Theknife edge 19d is arrange|positioned under theroller conveyor 5, and extends along the full width of the 3rd optical member sheet|seat F3S at least in the width direction of the 3rd optical member sheet|seat F3S. Theknife edge 19d winds the third optical member sheet F3S at an acute angle so as to be in sliding contact with the separator SS side of the half-cut third optical member sheet F3S.

第三光学构件片体F3S在刀口19d呈锐角折回之时，使第三光学构件F13从隔片SS分离。刀口19d与夹压辊21的面板输送下游侧相接近地被配置。通过刀口19d从隔片SS分离的第三光学构件F13一边与辊式输送机5所输送的液晶面板P的下表面重叠，一边被导入夹压辊21的一对贴合辊之间。The 3rd optical member sheet|seat F3S separates the 3rd optical member F13 from the spacer SS when 19 d of knife edges fold back at an acute angle. Theknife edge 19d is arranged close to the panel conveyance downstream side of thenip roller 21 . The 3rd optical member F13 separated from spacer SS by 19 d of knife edges is introduced between a pair of bonding roller of thenip roller 21, overlapping the lower surface of the liquid crystal panel P conveyed by theroller conveyor 5.

夹压辊21具有轴方向相互平行地被配置的一对贴合辊。Thenip roll 21 has a pair of bonding rolls arrange|positioned mutually in parallel to an axial direction.

在一对贴合辊之间形成有规定的间隙，该间隙内成为第三贴合装置18的贴合位置。在所述间隙内，第二单面贴合面板P12以及第三光学构件F13重叠在一起被导入。这些第二单面贴合面板P12以及第三光学构件F13一边在所述贴合辊间受夹压，一边被送出至面板输送下游侧。由此，形成在第二单面贴合面板P12上贴合有第三光学构件F13的两面贴合面板P13(参照图7)。A predetermined gap is formed between a pair of bonding rollers, and the inside of this gap becomes the bonding position of thethird bonding device 18 . In the said gap, the 2nd single-sided bonding panel P12 and the 3rd optical member F13 are superimposed and introduced. These 2nd single-sided bonding panel P12 and the 3rd optical member F13 are sent out to the panel conveyance downstream side, being pinched between the said bonding rolls. Thereby, the double-sided bonding panel P13 (refer FIG. 7) which bonded the 3rd optical member F13 to the 2nd single-sided bonding panel P12 is formed.

两面贴合面板P13经由未图示的缺陷检测装置被检测有无缺陷(贴合不良等)后，被输送至下游工序进行其他的处理。The double-sided bonded panel P13 is conveyed to a downstream process after having detected the presence or absence of a defect (bonding failure etc.) via the defect detection apparatus which is not shown in figure, and performs other processing.

在此，一般地，长条的光学膜(相当于各光学构件片F1、F2、F3)使得用二色性色素染色了的树脂膜单轴拉伸来制造，光学膜的光轴方向与树脂膜的延伸方向大致一致。但是，光学膜的光轴在光学膜整体中并不均一，在光学膜的宽度方向有稍许参差不齐。Here, in general, elongated optical films (corresponding to the respective optical member sheets F1, F2, and F3) are manufactured by uniaxially stretching a resin film dyed with a dichroic dye, and the optical axis direction of the optical film is aligned with the resin film. The extension direction of the film is approximately the same. However, the optical axis of the optical film is not uniform throughout the entire optical film, and is slightly uneven in the width direction of the optical film.

因此，在光学膜的宽度方向上贴合多个光学显示零件的情况下，按照光学膜的光轴方向进行光学显示零件的校准是理想的。Therefore, when bonding a plurality of optical display components in the width direction of the optical film, it is desirable to align the optical display components in accordance with the optical axis direction of the optical film.

这对抑制光学显示设备单位的光轴的参差不齐以及提高精彩度和对比度十分有效。This is very effective for suppressing the unevenness of the optical axis of the unit of the optical display device and improving the brilliance and contrast.

为了阻断除单一方向振动的光以外的光，例如，通过碘、二色性染料等将作为偏振膜的光学膜染色。另外，也可以在光学膜上进一步层压脱模膜或保护膜。In order to block light other than light vibrating in one direction, for example, an optical film as a polarizing film is dyed by iodine, a dichroic dye, or the like. In addition, a release film or a protective film may be further laminated on the optical film.

检测光学膜的光轴方向的检测装置具有：被配置在靠近光学膜的表面以及背面中的一个面的位置的光源；以及检偏振器，所述检偏振器被配置在靠近光学膜的表面以及背面中的另一个面的位置，并被配置在光源的相反侧。检偏振器通过接收从光源照射并透过光学膜的光，检测该光的强度，从而检测光学膜的光轴。检偏振器能够在例如光学膜的宽度方向移动，能够在光学膜的宽度方向的任意地方(根据使用条件选择的地方)检测光轴。The detection device that detects the optical axis direction of the optical film has: a light source that is arranged at a position close to one of the surface and the back surface of the optical film; The position of the other face in the back, and is arranged on the opposite side of the light source. The analyzer detects the optical axis of the optical film by receiving light irradiated from the light source and passing through the optical film, and detecting the intensity of the light. The analyzer can move, for example, in the width direction of the optical film, and can detect the optical axis at any position (place selected according to usage conditions) in the width direction of the optical film.

在本实施方式的情况下，由所述检测装置得到的各光学构件片F1、F2、F3的光轴方向的检测数据与各光学构件片F1、F2、F3的长度方向位置和宽度方向位置相关联地被存储在控制装置20的存储器中。该检测后，卷取各光学构件片F1、F2、F3，分别形成各卷材R1、R2、R3。以下，各光学构件片F1、F2、F3被总称为光学构件片FX、被贴合在各光学构件片F1、F2、F3的液晶面板P以及各单面贴合面板P11、P12被总称为光学显示零件PX。In the case of this embodiment, the detection data of the optical axis direction of each optical member sheet F1, F2, F3 obtained by the detection device is related to the longitudinal direction position and the width direction position of each optical member sheet F1, F2, F3 are stored in the memory of thecontrol device 20. After this detection, each optical member sheet|seat F1, F2, F3 is wound up, and each roll material R1, R2, R3 is formed, respectively. Hereinafter, each optical member sheet F1, F2, F3 is collectively referred to as an optical member sheet FX, and the liquid crystal panel P bonded to each optical member sheet F1, F2, F3 and each single-sided bonding panel P11, P12 are collectively referred to as an optical member sheet FX. Display part PX.

在此，构成光学构件片FX的偏振器件膜是单轴拉伸被例如二色性色素染色了的PVA膜而形成的，但由于拉伸时的PVA膜的厚度的不均匀或二色性色素的染色不均匀等，具有在光学构件片FX的宽度方向内侧和宽度方向外侧产生不同光轴方向的倾向。Here, the polarizer film constituting the optical member sheet FX is formed by uniaxially stretching a PVA film dyed, for example, with a dichroic dye. There exists a tendency for the optical axis direction to differ in the width direction inner side and the width direction outer side of the optical member sheet|seat FX, such as dyeing|staining nonuniformity.

因此，在本实施方式中，基于在控制装置20预先存储的光学构件片FX的各部分的光轴的面内分布的检测数据，进行贴合于此的光学显示零件PX的校准，并将光学显示零件PX贴合在光学构件片FX上。Therefore, in the present embodiment, based on the detection data of the in-plane distribution of the optical axis of each part of the optical member sheet FX stored in advance in thecontrol device 20, the calibration of the optical display parts PX bonded thereto is performed, and the optical display parts PX are aligned. The display part PX is bonded to the optical member sheet FX.

具体来说，在光学构件片FX中的贴合光学显示零件PX的部位的面内，例如找出相对于规定的基准轴(长度方向轴等)的角度最大的光轴和最小的光轴，将使这些各光轴所形成的角二等分的轴作为该部位的平均光轴，以该轴为基准进行光学显示零件PX的校准。Specifically, in the surface of the portion of the optical member sheet FX where the optical display component PX is bonded, for example, the optical axis with the largest angle and the smallest optical axis with respect to a predetermined reference axis (longitudinal axis, etc.) are found, The axis that bisects the angle formed by these respective optical axes is taken as the average optical axis of the site, and the alignment of the optical display part PX is performed with reference to this axis.

由此，即使在光学构件片FX的宽度方向的不同的位置上贴合光学显示零件PX的情况下，也能抑制光学构件片FX的光轴方向相对于光学显示零件PX的基准位置的参差不齐，能够使光轴公差大致为0°(允许公差是±0.25°)。Thereby, even when the optical display components PX are bonded at different positions in the width direction of the optical member sheet FX, the deviation of the optical axis direction of the optical member sheet FX with respect to the reference position of the optical display components PX can be suppressed. Alignment, the optical axis tolerance can be approximately 0° (allowable tolerance is ±0.25°).

另外，也可以边放卷光学构件片FX，边检测光轴方向，基于该检测数据进行光学显示零件PX的校准。又，上述种种的校准方法并不限定光学构件片FX的光轴方向是0°以及90°的情况，也可适用于光轴方向被设定为任意角度(根据光学显示零件的目的的角度)的情况。In addition, the optical axis direction may be detected while unwinding the optical member sheet FX, and alignment of the optical display components PX may be performed based on the detection data. In addition, the above-mentioned various alignment methods are not limited to the case where the optical axis direction of the optical member sheet FX is 0° and 90°, but can also be applied when the optical axis direction is set to an arbitrary angle (angle according to the purpose of the optical display component) Case.

又，图3示出在具有较广宽度的光学构件片FX的宽度方向上并排贴合三个光学显示零件PX的实例。本发明并不限定于图3示出的实例，也可以采用在光学构件片FX的宽度方向上并排贴合两个以下或四个以上的光学显示零件PX的结构，也可以采用在宽度方向排列多个宽度较窄的光学构件片FX，并在这些光学构件片FX上分别贴合光学表示零件PX的结构。Moreover, the example which bonded three optical display components PX side by side in the width direction of the optical member sheet|seat FX which has a wide width is shown in FIG. The present invention is not limited to the example shown in Fig. 3, also can adopt the structure that two or less or more than four optical display parts PX are bonded side by side on the width direction of optical member sheet FX, also can adopt to arrange in the width direction A plurality of narrow optical member sheets FX are bonded to each of these optical member sheets FX with the structure of optical display parts PX.

参照图4，液晶面板P具有：由例如TFT基板构成的长方形的第一基板P1；与第一基板P1相对配置的同样为长方形的第二基板P2；以及被封入第一基板P1和第二基板P2之间的液晶层P3。另外，在图示的情况中，有时省略剖面图的各层的剖面线。Referring to FIG. 4 , the liquid crystal panel P has: a rectangular first substrate P1 made of, for example, a TFT substrate; a rectangular second substrate P2 opposite to the first substrate P1; Liquid crystal layer P3 between P2. In addition, in the case of illustration, the hatching of each layer in a cross-sectional view may be omitted.

参照图6，使得第一基板P1的外周缘的三边沿着第二基板P2的相对应的三边，且使外周缘剩余的一边向第二基板P2的相对应的一边的外侧延伸。由此，在第一基板P1的所述一边侧设置有向第二基板P2的外侧延伸的电器零件安装部P5。Referring to FIG. 6 , three sides of the outer peripheral edge of the first substrate P1 are along corresponding three sides of the second substrate P2 , and the remaining side of the outer peripheral edge extends outside the corresponding side of the second substrate P2 . Thereby, the electrical component mounting part P5 extended to the outer side of the 2nd board|substrate P2 is provided in the said one side of the 1st board|substrate P1.

参照图5，第二切割装置16边用照相机16a等检测部检测显示区域P4的外周缘，边沿显示区域P4的外周缘等切割第一以及第二光学构件片F1、F2。在显示区域P4的外侧设置规定宽度的框缘部G，在该框缘部G的宽度内利用各切割装置16、19进行激光切割，所述框缘部G配置接合第一以及第二基板P1、P2的密封剂等。Referring to FIG. 5 , thesecond cutting device 16 cuts the first and second optical member sheets F1 and F2 along the outer periphery of the display region P4 while detecting the outer periphery of the display region P4 with a detection unit such as thecamera 16a. A frame portion G having a predetermined width is provided outside the display area P4, and laser cutting is performed within the width of the frame portion G by cuttingdevices 16 and 19. The frame portion G is arranged to join the first and second substrates P1. , P2 sealant, etc.

如图9所示，若单独激光切割树脂制的光学构件片FX，光学构件片FX的切割端t由于热变形产生膨胀或起伏。因此，在将激光切割后的光学构件片FX贴合至光学显示零件PX的情况下，光学构件片FX易产生混入空气或变形等贴合不良。As shown in FIG. 9, when the optical member sheet|seat FX made of resin is individually laser-cut, the cutting edge t of the optical member sheet|seat FX expands or undulates by thermal deformation. Therefore, when the optical member sheet|seat FX after laser cutting is bonded to the optical display component PX, bonding failures, such as air mixing and deformation|transformation, are easy to generate|occur|produce in optical member sheet|seat FX.

另一方面，如图8所示，在将光学构件片FX贴合在液晶面板P之后激光切割光学构件片FX的本实施方式中，光学构件片FX的切割端t被支承在液晶面板P的玻璃面。因此，由于不产生光学构件片FX的切割端t的膨胀或起伏等，且在向液晶面板P贴合光学构件片FX之后，因此不会产生所述的贴合不良。On the other hand, as shown in FIG. 8 , in this embodiment in which the optical member sheet FX is laser cut after the optical member sheet FX is bonded to the liquid crystal panel P, the cut end t of the optical member sheet FX is supported on the edge of the liquid crystal panel P. glass surface. Therefore, after bonding optical member sheet|seat FX to liquid crystal panel P, since expansion, undulation, etc. of the cut edge t of optical member sheet|seat FX do not generate|occur|produce, the said bonding defect does not generate|occur|produce.

在液晶面板P上切割光学构件片FX这样的情况下，激光加工机的切割线的偏差宽度(公差)比切割刀具的切割线的偏差宽度小。因此在本实施方式中，与使用切割刀具切割光学构件片FX的情况相比，能够缩小所述框缘部G的宽度，能够使液晶面板P小型化以及(或者)显示区域P4大型化。这样的光学构件片对如近年的智能手机或触屏终端那样的、限制壳体的尺寸且要求扩大显示画面的高性能移动信息终端的适用也是有效的。When cutting the optical member sheet|seat FX on liquid crystal panel P, the variation width (tolerance) of the cutting line of a laser processing machine is smaller than the variation width of the cutting line of a cutting blade. Therefore, in this embodiment, compared with the case where the optical member sheet|seat FX is cut|disconnected using a dicing blade, the width|variety of the said frame edge part G can be narrowed, and liquid crystal panel P can be miniaturized and (or) display area P4 can be enlarged. Such an optical member sheet is also effective for application to high-performance mobile information terminals that limit the size of a housing and require an enlarged display screen, such as recent smartphones or touch-panel terminals.

在此，由于在将光学构件片FX切割为整合到液晶面板P的显示区域P4的片材后输送到别的生产线并贴合在液晶面板P的情况下，所述片材以及液晶面板P各自的尺寸公差及这些相对贴合位置的尺寸公差重叠，因此缩小液晶面板P的框缘部G的宽度变得困难(扩大显示区域变得困难)。Here, when the optical member sheet FX is cut into a sheet integrated into the display area P4 of the liquid crystal panel P and then transported to another production line and bonded to the liquid crystal panel P, the sheet and the liquid crystal panel P each The dimensional tolerances and the dimensional tolerances of these relative bonding positions overlap, so it becomes difficult to narrow the width of the frame portion G of the liquid crystal panel P (it becomes difficult to expand the display area).

另一方面，在将光学构件片FX贴合在液晶面板后，按照显示区域P4切割光学构件片FX的情况下，只考虑切割线的偏差公差就能够缩小框缘部G的宽度公差(±0.1mm以下)。该点也可缩小液晶面板P的框缘部G的宽度(扩大显示区域成为可能)。On the other hand, after bonding the optical member sheet FX to the liquid crystal panel, when the optical member sheet FX is cut according to the display area P4, the width tolerance of the frame edge part G can be narrowed (±0.1 mm or less). This point also makes it possible to reduce the width of the frame portion G of the liquid crystal panel P (it becomes possible to expand the display area).

进一步，通过不用刀具而是用激光切割液晶面板P上的光学构件片FX，切割时的力度不输入至液晶面板P，在液晶面板P的基板的端缘很难产生裂缝或缺陷，提高对于热循环等的耐久性。同样的，由于不接触液晶面板P，对于电气零件安装部P5的损害也少。Furthermore, by cutting the optical member sheet FX on the liquid crystal panel P with a laser instead of a cutter, the strength during cutting is not input to the liquid crystal panel P, and it is difficult to generate cracks or defects at the edge of the substrate of the liquid crystal panel P, thereby improving thermal resistance. Durability of cycles etc. Similarly, since it does not touch liquid crystal panel P, there is little damage to electrical component mounting part P5.

又，第三贴合装置18将具有与显示区域P4对应的宽度的带状的第三光学构件片F3切割成规定长度而形成第三光学构件F13。第三贴合装置18一边与隔片SS一起输送该第三光学构件F13，一边在进行所述切割的生产线内将它们贴合于第二单面贴合面板P12。因此，与将按照显示区域P4加工了的偏光板输送至别的生产线这样的情况相比，第三光学构件F13的尺寸参差不齐或贴合参差不齐的影响得以抑制。Moreover, the3rd bonding apparatus 18 cuts the belt-shaped 3rd optical member sheet|seat F3 which has the width|variety corresponding to the display area P4 to predetermined length, and forms the 3rd optical member F13. The3rd bonding apparatus 18 bonds these to the 2nd single-sided bonding panel P12 in the line which performs the said dicing, conveying this 3rd optical member F13 together with the spacer SS. Therefore, compared with the case where the polarizing plate processed according to the display area P4 is conveyed to another production line, the influence of the size variation of the 3rd optical member F13 or the bonding variation is suppressed.

如图6所示，在用激光切割光学构件片FX(图6中的第二光学构件片F2)的情况下，例如将激光切割的起点pt1设定在显示区域P4的一个长边的延长线上，从该起点pt1首先开始切割所述一个长边。激光切割的终点pt2设定在激光绕显示区域P4一圈到达显示区域P4的起点侧的短边的延长线上的位置。起点pt1以及终点pt2被设定为在光学构件片FX的剩余部分留下规定的连接部分，从而能耐受卷取光学构件片FX时的张力。As shown in FIG. 6, in the case of cutting the optical member sheet FX (the second optical member sheet F2 in FIG. 6 ) with a laser, for example, the starting point pt1 of laser cutting is set on the extended line of one long side of the display area P4. , start cutting the one long side first from the starting point pt1. The end point pt2 of laser cutting is set at the position on the extension line of the short side on the starting point side where the laser light goes around the display area P4 and reaches the display area P4. The starting point pt1 and the end point pt2 are set so that a predetermined connection portion can be left in the remainder of the optical member sheet FX, and the tension at the time of winding up the optical member sheet FX can be tolerated.

In the system 1, it includes: laminatingdevices 12, 15. Thelaminating devices 12, 15 unwind strip-shaped optical display parts PX from the roll materials R1, R2 for the plurality of optical display parts PX conveyed on theroller conveyor 5. The optical member sheets F1 and F2 are sequentially bonded to the first optical member sheet F1 on the second optical member sheet F2 and the first faces (one of the front and back faces) of the plurality of liquid crystal panels P. Sheet F22, said optical member sheets F1, F2 have a width larger than the width of the display area of liquid crystal panel P in the part width direction perpendicular to the conveying direction of optical display part PX; and thesecond cutting device 16, said first Thesecond cutting device 16 cuts the opposing portion of the optical member sheet F1, F2 facing the display area P4 and the remaining portion outside the opposing portion, and cuts the optical member sheet F1, F2. The optical components F11 and F12 having a size corresponding to the display area P4 are produced, thereby cutting out a second single-sided laminated panel P12 from the second laminated sheet F22, and the second single-sided laminated panel P12 includes a single The liquid crystal panel P and the optical members F11, F12 overlapping with the liquid crystal panel P; For the second single-sided laminated panel P12, the strip-shaped third optical member sheet F3 having a width corresponding to the display area P4 in the width direction of the part and the spacer SS are put together from the third roll material R3 Each time the third optical member sheet F3 is unwound with a length corresponding to the display area P4, cutting along the width direction is performed on the third optical member sheet F3 to have a shape corresponding to the display area P4. After the size of the third optical member F13, the spacer SS is used as a carrier to transport a plurality of the third optical member F13, and at the same time, the third optical member F13 is bonded to the second single-sided bonding panel On the second surface of the liquid crystal panel P on P12 (the other surface of the surface opposite to the first surface, the front surface, and the back surface).

根据该结构，将具有与显示区域P4对应的宽度的带状的第三光学构件片F3切割成规定长度而形成第三光学构件F13，一边将与第三光学构件片F3一起放卷的隔片SS做为载体输送该第三光学构件F13，一边在进行所述切割的生产线内在液晶面板P贴合第三光学构件F13。因此，与将按照显示区域P4加工了的偏光板输送至别的生产线这样的情况相比，能够抑制第三光学构件F13的尺寸参差不齐或贴合参差不齐，缩小显示区域P4周边的框缘部G，谋求显示区域的扩大以及设备的小型化。According to this configuration, the strip-shaped third optical member sheet F3 having a width corresponding to the display area P4 is cut into a predetermined length to form the third optical member F13, and the spacer that is unwound with the third optical member sheet F3 SS transports this 3rd optical member F13 as a carrier, and bonds 3rd optical member F13 to liquid crystal panel P in the production line which performs said cutting. Therefore, compared with the case where the polarizing plate processed according to the display area P4 is transported to another production line, it is possible to suppress the size variation or bonding unevenness of the third optical member F13, and reduce the size of the frame around the display area P4. The edge G seeks to expand the display area and reduce the size of the device.

又，通过将贴合至液晶面板P后的光学构件片F1、F2的切割与残留隔片SS的半切割后的第三光学构件片F3的贴合相组合，能够谋求框缘部Ｇ的缩小和生产节拍时间的缩短。Furthermore, by combining the cutting of the optical member sheets F1 and F2 bonded to the liquid crystal panel P and the bonding of the third optical member sheet F3 after the half-cut with the spacer SS left, the size of the frame edge G can be achieved. and reduction in takt time.

又，上述光学显示设备的生产系统的所述第三贴合装置18具有：辊保持部19a，其将所述第三光学构件片F3和所述隔片SS一起放卷；切割装置19c，其对所述第三光学构件片F3实施切割并做成所述第三光学构件F13；第二检测照相机23，其在与对所述第三光学构件片F3实施切割的切割位置相比，在所述第三光学构件片F3的放卷方向上向下游侧隔开与一个所述第三光学构件F13对应的距离的位置，对通过所述切割形成在所述第三光学构件片F3上的切割线进行检测；以及控制装置20，在从所述切割位置向下游侧隔开一个所述第三光学构件F13的距离的检测位置检测到所述切割线时，控制装置20根据所述切割线的位置对所述切割位置和所述检测位置之间的距离进行调整。In addition, thethird laminating device 18 of the production system of the above-mentioned optical display device has: aroll holder 19a that unwinds the third optical member sheet F3 and the spacer SS together; acutting device 19c that The third optical member sheet F3 is cut and made into the third optical member F13; thesecond detection camera 23 is at the cutting position compared with the cutting position of the third optical member sheet F3. In the unwinding direction of the third optical member sheet F3, the position is separated from the downstream side by a distance corresponding to one third optical member F13, and the cuts formed on the third optical member sheet F3 by the cutting and thecontrol device 20 detects the cutting line at a detection position separated from the cutting position by a distance of the third optical member F13 to the downstream side, thecontrol device 20 detects the cutting line according to the The position adjusts the distance between the cutting position and the detection position.

Moreover, even if an error occurs in the unwinding amount of the 3rd optical member sheet|seat F3, the said error can be corrected (absorbed) by the relative movement of thecutting device 19c based on the detection information of the2nd detection camera 23. Therefore, the precision of the length of the 3rd optical member F13 can be ensured, and it can respond also to the cutting of the 3rd optical member F13 which differs in length.

The 3rd optical member sheet|seat F3S is cut|disconnected (that is, only the 3rd optical member sheet|seat F3 is cut|disconnected). Thecutting device 119c adjusts the advancing and retreating position of the cutting blade so that the spacer SS is not broken by the tension acting during the conveyance of the third optical member sheet F3S.

在此，在刀口119d的顶端部附近、即第三贴合装置118的贴合位置附近的面板输送上游侧的部位，设置有对该部位的第三光学构件F13的放卷方向下游侧的切割端进行检测的第一检测照相机122。第一检测照相机122的检测信息被发送给控制装置120。控制装置120例如在第一检测照相机122检测到第三光学构件F13的下游侧端的时刻使输送装置119暂时停止。其后，在第一检测照相机122检测到第二单面贴合面板P12的下游侧端的时刻，控制装置120使输送装置119驱动，使第二单面贴合面板P12和第三光学构件F13同步并能够将它们导入至第三贴合装置118的贴合位置。Here, near the front end of theknife edge 119d, that is, near the bonding position of thethird bonding device 118, on the upstream side of the panel conveyance, a cut is provided on the downstream side of the third optical member F13 in the unwinding direction.

Thecontrol device 120 temporarily stops thetransport device 119 when thefirst detection camera 122 detects the downstream end of the third optical member F13, for example. Thereafter, when thefirst detection camera 122 detects the downstream side end of the second single-sided bonding panel P12, thecontrol device 120 drives the conveyingdevice 119 to synchronize the second single-sided bonding panel P12 and the third optical member F13. And they can be introduced into the bonding position of the3rd bonding apparatus 118.

另一方面，在第一检测照相机122的放卷方向上游侧、即相比切割装置119c位于一个第三光学构件F13程度的所述放卷方向下游侧的部位，同样设置有对第三光学构件F13的放卷方向下游侧的切割端进行检测的第二检测照相机123。第二检测照相机123的检测信息也被发送给控制装置120。控制装置120例如在通过切割装置119c进行了第三光学构件片F3的切割后将其放卷，在第二检测照相机123检测到该切割端(第三光学构件片F3的最上游侧的切割线)的时刻，使输送装置119暂时停止。此时，采用切割装置119c进行第三光学构件片F3的切割。即、沿着第二检测照相机123的检测位置(相当于第三光学构件片F3上的第二检测照相机123的光轴延长位置)与切割装置119c的切割位置(相当于第三光学构件片F3上的切割装置119c的切割刀具进退位置)之间的片材输送路径的距离相当于第三光学构件F13的长度。On the other hand, on the upstream side of the unwinding direction of thefirst detection camera 122, that is, on the downstream side of the unwinding direction by one third optical member F13 relative to thecutting device 119c, a pair of third optical members is also provided. The2nd detection camera 123 which detects the cutting edge of the downstream side of the unwinding direction of F13. The detection information of thesecond detection camera 123 is also sent to thecontrol device 120 . Thecontrol device 120, for example, unwinds the third optical member sheet F3 after cutting it by thecutting device 119c, and thesecond detection camera 123 detects the cut end (cutting line on the most upstream side of the third optical member sheet F3). ), temporarily stop the conveyingdevice 119. At this time, cutting of the 3rd optical member sheet|seat F3 is performed using thecutting apparatus 119c. That is, along the detection position of the second detection camera 123 (corresponding to the optical axis extension position of thesecond detection camera 123 on the third optical member sheet F3) and the cutting position of thecutting device 119c (corresponding to the third optical member sheet F3 The distance of the sheet conveying path between the cutting blade advancing and retreating positions of thecutting device 119c on the upper surface corresponds to the length of the third optical member F13.

又，切割装置119c被设定为能够沿着第三光学构件片体F3S的片材输送路径移动。通过该移动，沿着第二检测照相机123的检测位置与切割装置119c的切割位置之间的片材输送路径的距离发生变动。切割装置119c的移动通过控制装置120控制，例如在采用切割装置119c进行第三光学构件片F3的切割之后将第三光学构件片F3放卷了一个第三光学构件F13程度的距离时，其切割端偏离规定位置的情况下，通过切割装置119c的移动来修正该偏差。Moreover, thecutting device 119c is set so that it can move along the sheet|seat conveyance path of the 3rd optical member sheet|seat F3S. This movement changes the distance along the sheet conveyance path between the detection position of thesecond detection camera 123 and the cutting position of thecutting device 119c. The movement of thecutting device 119c is controlled by thecontrol device 120. For example, after the third optical member sheet F3 is cut by thecutting device 119c, the third optical member sheet F3 is unwound by a distance of a third optical member F13. When the end deviates from a predetermined position, the deviation is corrected by moving thecutting device 119c.

另外，也可以通过切割装置119c的移动来对应长度不同的第三光学构件F13的切割。又，可以做成通过使切割装置119c以及第二检测照相机123的至少一方在片材输送方向移动，来进行所述修正或第三光学构件F13的长度变更的结构。又，切割装置119c和第二检测照相机123相互接近，但为了防止伴随着切割装置119c的移动等的第二检测照相机123的振动，切割装置119c和第二检测照相机123分别由另外的框架来支承比较理想。In addition, the cutting of the third optical member F13 having different lengths may be supported by the movement of thecutting device 119c. In addition, the correction or the length change of the third optical member F13 may be performed by moving at least one of thecutting device 119c and thesecond detection camera 123 in the sheet conveyance direction. Also, thecutting device 119c and thesecond detection camera 123 are close to each other, but in order to prevent vibration of thesecond detection camera 123 accompanying the movement of thecutting device 119c, thecutting device 119c and thesecond detection camera 123 are supported by separate frames respectively. ideal.
