Embodiment

By accompanying drawing following detailed description is studied, embodiments of the invention will become and be perfectly clear.

Fig. 2 A is to shown in the 2C being basic driver principle according to the EOC-LCD of first embodiment of the invention.Fig. 3 A is to shown in the 3C being basic driver principle according to the EOC-LCD of second embodiment of the invention.

Referring to Fig. 2 A to 2C and Fig. 3 A to 3C, form a pair oftransparent glass substrate 10 and 20 that respectively has an alignment films 90 relative to each other.On the inside surface of the followingsubstrate 10 of twosubstrates 10 and 20, form two band electrodes (linear electrode) 30 and 40. parallel to each other and between twoglass substrate 10 and 20, inject liquid crystal material,liquid crystal molecule 80 vertical planes that form aliquid crystal layer 70. liquid crystal layers 70 are arranged, therefore perpendicular to twosubstrates 10 and 20.liquid crystal molecules 80 with respect to twosubstrates 10 and 20, can have a pre-tilt angle. twoelectrodes 30 and 40 can be transparent or opaque conductive materials. twopolaroids 50 and 60 to carry out polarization by light stick to respectively on the outside surface ofglass substrate 10 and 20.

In general, be a pixel capacitors one of in twoelectrodes 30 and 40, be used for different data-signals is applied to each pixel unit, another then is a public electrode, is used for a common signal is applied to all pixel units.In addition, each pixel capacitors all be formed at each pixel in the terminal of switching device (as thin film transistor (TFT)) link to each other.

The dielectric anisotropy amount Δ ε of the liquid crystal material ofliquid crystal layer 70 is preferably positive, but also can bear.Liquid crystal material can be nematic liquid crystal, chiral nematic liquid crystal and have left hand or one of the nematic liquid crystal of right hand chiral doping matter.

In addition, can rub, therebyliquid crystal molecule 80 is tilted along predetermined direction, perhaps two alignment films 90 not rubbed one or two alignment films 90.Friction is carried out on can be in any direction.But when two alignment films are all rubbed, preferably along opposite two alignment films of direction friction.

Thepolaroid 50 and 60 the axis of homology are parallel to each other or orthogonal.

In addition,electrode 30 and 40 width preferably at 1 μ m between the 10 μ m, the distance between theelectrode 30 and 40 preferably at 2 μ m between the 20 μ m, and the thickness ofliquid crystal layer 70 is preferably between 1 to 15 μ m.

In 2C, liquid crystal material is the pure nematic liquid crystal with dielectric anisotropy at Fig. 2 A.In 3C, liquid crystal material is to have chiral doping matter and the nematic liquid crystal of positive anisotropy amount or the chiral nematic liquid crystal with positive anisotropy amount at Fig. 3 A.

Referring to Fig. 2 A and 3A, when added electric field not, theliquid crystal molecule 80 ofliquid crystal layer 70 is under the effect of alignment films 90 dipole-dipole forces, perpendicular to twosubstrates 10 and 20.

See through the light that sticks to down thepolaroid 50 on thesubstrate 10, byliquid crystal layer 70, its polarization state is constant.If the axis of homology of twopolaroids 50 and 60 is parallel to each other, then this light is equally by sticking to thepolaroid 60 on the substrate 20.And if the axis of homology of twopolaroids 50 and 60 is orthogonal, then this light is stopped by thepolaroid 60 on thelast substrate 20.

Shown in Fig. 2 B and the 3B is when forming sufficient electric field, the ordered state ofliquid crystal molecule 80, and Fig. 2 C and 3C are its elevation drawing.The electric field that twoelectrodes 30 of distance and 40 equidistant points (interphase) are located is basically parallel to twosubstrates 10 and 20, and perpendicular to twoelectrodes 30 and 40.When described electric field leaves above-mentioned point, and when one ofelectrode 30 or 40 were mobile, then electric field was bent downwardly gradually.That is to say that electric field is a downward parabolic shape.

At this moment, because nematic liquid crystal material has positive dielectric anisotropy amount, the major axis ofliquid crystal molecule 80 is orientated along direction of an electric field.But near theliquid crystal molecules 80substrate 10 and 20 still keep its original state, these liquid crystal molecules since the dipole-dipole force of alignment films 90 greater than electric field action power, and be oriented in andsubstrate 10 and 20 perpendicular directions.Therefore, when utilizing pure nematic liquid crystal material, the liquid crystal dipole continues to change with balance electric field action power and dipole-dipole force.

In addition, the liquid crystal material layer between theelectrode 30 and 40 has two neighboring regions at least.Whereinliquid crystal molecule 80 orientation in each zone is identical, and theliquid crystal molecule 80 in two zones is then owing to the electric field between twoelectrodes 30 and 40 generally speaking has parabolic shape, and is symmetric orientation with respect to the interphase in these two zones.As mentioned above, interphase is positioned at andelectrode 30 and 40 equidistant places.

Therefore, referring to Fig. 2 B and 2C, because the phase place optical path difference of the light byliquid crystal layer 70 has obtained compensation symmetrically, so increased perpendicular to the visual angle on twoelectrodes 30 and 40 directions.And because the refraction coefficient onliquid crystal molecule 80 short-axis directions does not almost have change, so the visual angle that is parallel onelectrode 30 and 40 directions has also increased.

On the other hand, because it is parallel with the electric field that place, 40 equidistant plane forms with substrate atdistance electrode 30, therefore because electric field action power is perpendicular with the long axis direction perpendicular to theliquid crystal molecule 80 of substrate orientation, thereby form a discrete interphase at above-mentioned interphase place, liquid crystal molecule wherein can not rotate.

Next, shown in Fig. 3 B and 3C, when the pure nematic liquid crystal that replaces Fig. 2 A with chiral nematic liquid crystal or nematic liquid crystal with chiral doping matter in 2C, produced different effects.As previously mentioned, apart from twoelectrodes 30 and 40 equidistant interphase places, also form the discontinuity zone thatliquid crystal molecule 80 can not rotate.But it is, therefore also not exclusively symmetrical between the arrangement of theliquid crystal molecule 80 in the discontinuity zone both sides mutually because the major axis ofliquid crystal molecule 80 under the effect of electric field action power, dipole-dipole force and chirality acting force variation has taken place.

That is to say that in the middle of Fig. 2 C, when viewed from above, the major axis ofliquid crystal molecule 80 is orientated perpendicular toelectrode 30 and 40; On the contrary, in Fig. 3 C, liquid crystal molecule in the discontinuity zone bothsides 80 counterclockwise or turn clockwise.At this moment, withelectrode 30 direction parallel with vertical with 40 on can obtain a wide angular field of view.

Under above-mentioned state, by adhering to down the polarized light of thepolaroid 50 on thesubstrate 10, when passingliquid crystal layer 70, its polarization state rotates along with reversing of liquid crystal dipole.

In the above two kinds of cases, by the interval between control dielectric anisotropy amount, thesubstrate 10 and 20, or the pitch ofliquid crystal molecule 80, polarization state is revolved turn 90 degrees.In the case, if the axis of homology of twopolaroids 50 and 60 is parallel to each other, light is subjected to adhering to stopping ofpolaroid 60 on the substrate 20.And if the axis of homology of twopolaroids 50 and 60 is orthogonal, light is then by thepolaroid 60 on thelast substrate 20.

Generally speaking, in the EOC-LCD according to the embodiment of the invention,liquid crystal molecule 80 is with respect to the discontinuity zone symmetric offset spread.Therefore, the light along the transmission of direction A among Fig. 2 B and the 3B and direction B passes theliquid crystal molecule 80 formed passages by aligned identical.Therefore, owing to, formed optical path difference with respect to passing light, so can obtain a wide angular field of view in much at one mode.

LCD at the above-mentioned type can carry out various variations to the structure and the arrangement of electrode, can form the electrode shown in Figure 4 and 5.Describe the structure and the arrangement of electrode below in detail.

Referring to Figure 4 and 5, in a pixel, along continuous straight runs forms agate line 100, and forms adata line 200 perpendicular to gate line 100.Be parallel togate line 100 and form a public electrode wire, promptly the firsthorizontal electrode line 32 forms a pixel capacitors line, the i.e. secondhorizontal electrode line 42 and be parallel tofirst electrode wires 32 in each pixel.Near the point of crossing ofgate line 100 anddata line 200, form a thin film transistor (TFT) (TFT).First end of TFT links to each other withgate line 100, and second end links to each other withdata line 200, and the 3rd end links to each other with the secondhorizontal electrode line 42.

In Fig. 4, as mentioned above, in each pixel, along continuous straight runs forms first level parallel to each other and the secondhorizontal electrode line 32 and 42.Suppose that with four electrodes be a unit, for example in two pixels on the upper right corner and the lower left corner, formfirst electrode 33 parallel to each other andsecond electrode 43 in diagonal positions.First andsecond electrodes 33 and 43 all vertically are connected to respectively on the firsthorizontal electrode line 32 and the secondhorizontal electrode line 42.

In two pixels of remainder, on its opposite side, form the firstvertical electrode line 31 and the secondvertical electrode line 41, describedelectrode wires 31 links to each other with the secondhorizontal electrode line 42 with the firsthorizontal electrode line 32 respectively with 41.In addition,first electrode 30 begins to extend from the firsthorizontal electrode line 32 and the first vertical electrode line, 31 places, forms a predetermined angle with the firsthorizontal electrode line 32 and the first vertical electrode line 31.Second electrode 40 that extends from the secondhorizontal electrode line 42 and the second vertical electrode line, 41 places is parallel tofirst electrode 30 and forms, and eachsecond electrode 40 all is arranged between twofirst electrodes 30.

Therefore, first andsecond electrodes 33 and 43 in a pixel, not parallel to each other with first andsecond electrodes 30 and 40 in the adjacent image point, but form a predetermined angle each other.

In Fig. 5, in each pixel, along continuous straight runs forms the first and secondhorizontal electrode lines 32 and 42 parallel to each other.The first and secondvertical electrode lines 31 are located vertical extension from the first and secondhorizontal electrode lines 32 with 42 opposite end respectively with41.First electrode 36 is made up of first 34 andsecond portion 35, and first 34 extends vertically downward from the firsthorizontal electrode line 32, and thesecond portion 35 that links to each other with first is bending to the right then.The part of the firstvertical electrode line 31 also is used as the first 34 offirst electrode 36, and from a plurality ofbranches 37 that the firstvertical electrode line 31 extends, forms abreast withsecond portion 35.

Second electrode 46 is made of first 44 and second portion 45.First 44 from the secondhorizontal electrode line 42 and the extension of the second vertical electrode line, 41 places is formed at therebetween, and is parallel to thesecond portion 35 offirst electrode 36; Thesecond portion 45 that extends from first 44 places, the first 34 that is parallel tofirst electrode 36 forms.The part of the secondvertical electrode line 41 also can be used as thesecond portion 45 of second electrode 46.That is to say that first andsecond electrodes 36 and 46 parallel to each other all bend in each pixel.

As mentioned above, by in a pixel unit or a pixel, forming electrode on all directions, can make the major axis of liquid crystal molecule be oriented in a plurality of directions, thereby obtain a wide angular field of view.

Hereinafter explain EOC-LCD example according to the embodiment of the invention.

Example 1

, and the final visual angle under every kind of situation measured asliquid crystal layer 70 with the nematic liquid crystal with chiral doping matter and pure nematic liquid crystal.

The refraction ansiotropy amount Δ n ofliquid crystal layer 70 is 0.09, and the thickness of liquid crystal layer is 4.5 μ m, and alignment films 90 is rubbed.In addition, twoelectrodes 30 and 40 are that along continuous straight runs forms, and thepolaroid 50 that adheres on twosubstrates 10 and 20 outside surfaces becomes one 90 to spend angles mutually with 60 the axis of homology.The axis of homology of one of them polaroid is with respect to twoelectrodes 30 and 40 one-tenth miter angles, and the axis of homology of another polaroid is with respect to twoelectrodes 30 and 40 one-tenth 135 degree angles.The right side of horizontal direction is set at 0 degree, comes these angles are measured.

Fig. 6 is when use contains the nematic liquid crystal of 0.1% chiral doping matter, the EOC-LCD visual angle figure that is obtained.Contrast is 10 o'clock, and measured visual angle, level side is 80 degree, and the vertical direction visual angle is 76 degree.

Fig. 7 is when using pure nematic liquid crystal, the visual angle figure of EOC-LCD.Contrast is 10 o'clock, and measured horizontal direction and vertical direction visual angle all are 76 degree.

When contrast settings was 60, for these two kinds of situations, measured visual angle all surpassed 120 degree on diagonal.

Example 2

Keep with example 1 in the identical state of state, the alignment films 90 that is formed on twosubstrates 10 and 20 has been passed through friction, all final visual angle is measured under every kind of situation.

Fig. 8 be the alignment films 90 on being formed atsubstrate 20 rub along 135 degree angular direction and alignment films 90 when being formed at downsubstrate 10 on when 315 spend angular direction and rub, the visual angle figure of the EOC-LCD that is obtained.

Fig. 9 be on being formed atsubstrate 20 alignment films 90 along the miter angle direction rub and alignment films 90 on being formed at downsubstrate 10 when 225 degree angular direction rub, the visual angle figure of the EOC-LCD that is obtained.

Shown in Fig. 8 and 9, by as mentioned above alignment films being rubbed, can reduce the poor of level and vertical direction upward angle of visibility and diagonal upward angle of visibility, thereby can obtain the visual angle of uniformity more.

Example 3

Keep with example 1 in the identical state of state, adhere topolaroid 50 on twosubstrates 10 and 20 outside surfaces and 60 direction of orientation by change, come the visual angle is measured.

Shown in Figure 10 is, when the axis of homology that will adhere to thepolaroid 60 onsubstrate 20 outside surfaces is arranged to become miter angle with twoelectrodes 30 with 40 direction, and when the axis of homology of thepolaroid 50 on will adhering to downsubstrate 10 outside surfaces is arranged to become 135 degree angles with 40 direction with twoelectrodes 30, the visual angle figure of resulting EOC-LCD.

Shown in Figure 11 is, when the axis of homology that will adhere to thepolaroid 60 onsubstrate 20 outside surfaces is arranged to 30 degree angles, and the axis of homology of thepolaroid 50 when will adhering to downsubstrate 10 outside surfaces on is arranged to 120 when spending angles, the visual angle figure of resulting EOC-LCD.

Described in example 1, when contrast was 60, measured visual angle all surpassed 120 degree on cornerwise four direction among Figure 10, and when contrast was 10, measured visual angle all was 80 degree on each direction.When the result among Figure 10 and Figure 11 was compared, the size that can find the visual angle depended on the angle between the electrode and the polaroid axis of homology.Therefore, in all sorts of ways and regulate the direction of the electrode direction and the polaroid axis of homology, on each direction, can both obtain an almost consistent visual angle.

Example 4

Keep with example 1 in the identical state of state, as shown in figure 12, in the time of on will bearing the outside surface that uniaxial compensation film is attached at twosubstrates 10 and 20, the visual angle is measured.Compensate film is used to compensate the resident phase differential of optical path difference (delay).

As shown in figure 13, when not using compensatefilm 100, measured visual angle is 80 degree.Shown in Figure 14 is, when use has the compensatefilm 100 of 40nm light path difference, and measured visual angle.Shown in Figure 15 is, when use has the compensatefilm 100 of 80nm light path difference, and measured visual angle.Shown in Figure 16 is, when use has the compensatefilm 100 of 120nm light path difference, and measured visual angle.

In Figure 14 to 16, when usingcompensation film 100, contrast is that 10 o'clock visual angle increases to 60 degree.

As can be seen from the above results, the interval between twosubstrates 10 and 20 and the light path difference of compensatefilm 100 are set, on each direction, can both obtain visual angle greater than 60 degree by optimization.The light path difference of compensate film is preferably between 30 to 500nm.

Although the embodiment of the invention is employed is a negative uniaxial compensation film, and positive uniaxial compensation film, biaxial compensation film, to have the compensate film of mixed structure or have the twist structured film of repaying all be operable.

In addition, although in an embodiment of the present invention, compensatefilm 100 is attached on twosubstrates 10 and 20, and it also can only be attached on the substrate.

Example 5

Electro-optical characteristic is measured.Asliquid crystal layer 70, alignment films 90 is through friction with pure nematic liquid crystal, and correspondingly twoelectrodes 30 and 40 width are respectively 5 μ m.

Figure 17 be according to an embodiment of the invention between the substrate at interval, distance and apply graph of a relation between the voltage three between the electrode.

At this, V_MaxBe the driving voltage that obtains maximum transmission rate, T_MaxBe maximum transmission rate, t_OnBe the response time of liquid crystal molecule when power connection, and t_OffBe the response time of liquid crystal molecule when dump, t_Tot=t_On+ t_Off, V₁₀Be when transmissivity be peaked drivingvoltage 10% time, and V₉₀Be when transmissivity be peaked driving voltage 90% time.

In Figure 17, when the interval between twosubstrates 10 and 20 between 3 to 6 μ m, and when the distance between twoelectrodes 30 and 40 is 8 or 10 μ m, the driving voltage that obtains maximum transmission rate is 6 to 30V.

As mentioned above, suitably regulate the interval between distance between electrodes and two substrates, can reduce driving voltage.

In the EOC-LCD according to the embodiment of the invention, two electrodes are formed at respectively in one of two substrates, and liquid crystal molecule is perpendicular to electrode orientation, and the liquid crystal dipole is by the parabolic type electric field driven that forms between two electrodes.At this moment, the liquid crystal layer liquid crystal molecule symmetric orientation on the equidistant interphase of each electrode.Therefore, because the light optical path difference has obtained compensation symmetrically, thereby can obtain the wide region visual angle.

Shown in Figure 18 and 23, be preferably formed as a serrate electrode in a pixel or in the adjacent image point, thereby obtain a display performance preferably.Hereinafter describe the structure and the arrangement of electrode in the rectangular pixel in detail.

Shown in Figure 18 and 19, in each pixel, asfirst electrode wires 32 of public electrode wire and parallel to each other assecond electrode wires 42 of pixel capacitors line.

In the embodiment of the invention shown in Figure 19, the first and second parallel relative to eachother electrode wires 32 and 42 are all extended according to alternating direction along pixel rows and row.Therefore, the electrode wires in all pixels adjacent with the pixel with a transverse electric polar curve all extends longitudinally.

In the embodiment of the invention shown in Figure 20 and 21, first electrode and second electrode in each pixel all extend along diagonal.

As shown in Figure 20 and 21,first electrode wires 32 hasOrShape, this is owing to electrode is formed from a summit along laterally reaching longitudinal extension.Second electrode wires 42 hasOrShape, this is owing to electrode wires is formed along laterally reaching longitudinal extension from cornerwise another summit with respect to above-mentioned summit.First andsecond electrodes 32 and 33 have rotational symmetry with respect to the pixel diagonal line.

First electrode 33 that is parallel to each other andsecond electrode 43, edge andelectrode wires 32 and 33 angled directions are extended fromfirst electrode wires 32 and second electrode wires, 42 places, and are staggered.In the embodiment of the invention shown in Figure 20, along on the line direction of pixel,electrode 33 and 34 in the pixel, withelectrode 33 and 34 in the adjacent image point at angle,first electrode 33 andsecond electrode 43 in the same row then extend along equidirectional.On the other hand, in the embodiment of the invention shown in Figure 21, along on pixel rows and the column direction, theelectrode 33 and 43 in the pixel all with adjacent image point inelectrode 33 and 43 at angle.

In the embodiment of the invention shown in Figure 22, pixel has parallelogram shape.

As shown in Figure 22,first electrode wires 32, it is a public electrode wire,second electrode wires 42, it is the pixel capacitors line, they are parallel to each other and along horizontal expansion.First electrode 33 andsecond electrode 43 that links to each other with 42 with first andsecond electrode wires 32 respectively is staggered and parallel to each other, and their bearing of trend is neither laterally neither be vertical.The length of electrode is identical, so pixel has parallelogram shape.Electrode 33 in the delegation and 43 extends along same direction, but theelectrode 33 in the adjacent lines extends along different directions with 43.For example, as shown in Figure 22,electrode 33 and 43 vertical direction with respect toelectrode wires 32 and 42 in first row are tilted to the right, and theelectrode 33 and 43 in second row then is tilted to the left, therefore,first electrode 33 andsecond electrode 43 form a serrate along each pixel rows direction.
