Now, the technique performed it is described in detail in step S140.In step S140, will be in step S110 and step The main oriented material applied in S120 with about 80 DEG C to about 110 DEG C preliminary heating about 100 seconds to about 140 seconds, more excellent Selection of land was with about 95 DEG C of preliminary heating about 120 seconds.During preliminary heating, the solvent volatilization of main oriented material, have vertical The monomer of the imidizate of orientation characteristic is orientated along the direction with lower vertical, thus forms main oriented layer.
After preliminary heating, by main oriented material with about 200 DEG C to about 240 DEG C post bake about 1000 seconds extremely About 1400 seconds, more preferably heat about 1200 seconds with about 220 DEG C.During post bake, main oriented material is hardened, Thus form main oriented layer.
After post bake, main oriented layer deionized water (DIW) is cleaned, it is possible to further with isopropanol (IPA) Clean.After the washing, main oriented layer is made to be dried.After drying, lower display floater 100 or on shape on display floater 200 Become liquid crystal layer.Liquid crystal layer can have containing liquid crystal molecule described above and the mixture of photo-hardening agent described above, ZSM-7160 mixture, DS-09-9301 mixture or liquid crystal molecule and the compound of photo-hardening agent described above.Pass through Lower display floater 100 and upper display floater 200 are assembled by sealant with the liquid crystal molecule being included in and photo-hardening agent.
After assembling, in order to improve ambiguity and the uniformity of liquid crystal molecule, can be by lower display floater 100 and upper aobvious Show that panel 200 is annealed about 60 minutes to about 80 minutes in the room of about 100 DEG C to about 120 DEG C.
In next step S150, after assembling, photo-hardening layer 35 is become by the photo-hardening agent of photo-hardening.Light is hard Change layer 35 and main oriented layer 33 constitutes lower plate alignment films 291.
In step S152 of step S150, formed in liquid crystal layer 3 before forming the lower plate photo-hardening layer 35 of hardening Electric field, is then exposed technique.These will be described in detail now.If providing voltages to be positioned at lower display floater Pixel electrode 191 on 100 and the common electrode 270 being positioned on display floater 200, then form electric field in liquid crystal layer 3.
Now, the method being used for according to an exemplary embodiment of the present invention forming electric field in liquid crystal layer 3 by description.The party Method includes for providing the method for direct current (DC) voltage and for the method providing multilevel voltage.First, will describe with reference to Fig. 7 A For the method providing D/C voltage to LCD board component 300.If " TA1 " in the period to LCD board component The gate line 121 of 300 and data wire 171 provide the first predetermined voltage V1, then pixel electrode 191h and 191l is provided with One voltage V1.Now, the voltage of ground voltage or about zero volt (0V) is provided to common electrode 270." TA1 " period is of about 1 second extremely About 300 seconds, more preferably it is of about 100 seconds.First voltage V1 is of about 5V to about 20V, is more preferably of about 7V extremely About 15V.
Now, will be described in the liquid crystal molecule being orientated in the period at " TA1 " by the electric field of generation in liquid crystal layer 3 The movement of 31." TA1 " period is the liquid crystal molecule 31 period along the direction orientation of fringe field.Owing to providing pixel electrode The voltage of 191h and 191l and offer produce electric field to the difference in voltage of common electrode 270, so having refraction in liquid crystal layer 3 The anisotropic liquid crystal molecule of rate 31 is orientated due to this electric field.Because the edge of pixel electrode 191h and 191l includes that differential props up 197h and 197l, micro chink 199h and 199l, vertical coupling part 193h and 193l and horizontal connecting portions 194h and 194l, As it is shown on figure 3, so pixel electrode edge makes electric field distortion, and in liquid crystal layer 3, form fringe field.Due to edge electricity , the major axis of liquid crystal molecule 31 tends to tilting along the direction of the edge-perpendicular propping up 197 with differential.It follows that because of by adjacent The direction of horizontal component that differential props up the fringe field that the edge of 197h and 197l produces is opposite each other, and differential prop up 197h and Interval W (such as, the width W between micro chink 199h and 199l) between 197l is narrow, so liquid crystal molecule 31 divides due to level Measure and tend to the direction along electric field and tilt.But, because the edge of vertical coupling part 193h and 193l and pixel electrode 191 The fringe field that produces of the edge of horizontal connecting portions 194h and 194l in terms of intensity, prop up 197h's and 197l more than differential The fringe field that edge produces, so the longitudinal direction that liquid crystal molecule 31 finally props up 197h and 197l with differential tilts abreast. In other words, (such as, differential props up the longitudinal direction side of 197h and 197l to the normal orientation of liquid crystal molecule 31 and relatively large fringe field To) tilt abreast.Parallel differential props up the most inclined angle of liquid crystal molecule 31 in the region at 197 places, thus shape Become a farmland.Prolong along 4 different directions in the first sub-pixel 190h or the second sub-pixel 190l of Fig. 3 because differential props up 197 Stretch, so the liquid crystal molecule 31 near pixel electrode 191 tilts along 4 different directions, and pixel electrode 191h and 191l In each there are four farmlands.If pixel PX has substantial amounts of farmland, then the side visibility of liquid crystal indicator can be Excellent.
Then, provide predetermined exposure voltage in the period at " TD1 " irradiating light to LCD board component 300, by This liquid crystal molecule 31 is orientated at steady-state, performs field exposure technology at " TD1 " during the period.Exposure voltage can be with " TA1 " first voltage V1 in the period is identical." TD1 " period be of about 50 seconds to about 150 seconds, be more preferably of about 90 Second.
In an alternative illustrative embodiment, pixel electrode 191 can be provided with ground voltage or the voltage of about 0V, common-battery Pole 270 can be provided with the first voltage V1 or exposure voltage.
Being used for LCD board component according to another exemplary embodiment of the present invention will be described in detail with reference to Fig. 7 B 300 methods that multilevel voltage is provided.Because the description of " TA1 " period the most in fig. 7 is described in detail by liquid crystal layer The movement of the liquid crystal molecule 31 that the electric field produced in 3 causes, describes so eliminating it.
If providing predetermined second voltage, then second voltage to gate line 121 and data wire 171 at " TA2 " in the period Pixel electrode 191h and 191l is provided to.Now, the voltage of ground voltage or about zero volt (0V) is provided to common electrode 270.The Two voltages are " TA2 " voltage in the period, and are made up of low-voltage and high voltage V2.Second voltage is alternately provided sub-pixel Electrode 191h and 191l, and there is the about 0.1Hz frequency to about 120Hz.Low-voltage can be ground voltage or 0V, high voltage V2 is preferably higher than the input operating range of liquid crystal indicator.High voltage V2 is of about 5V to about 60V, the biggest About 30V to about 50V." TA2 " period be of about 1 second to about 300 seconds, be more preferably of about 60 seconds.At " TA2 " in the period The time keeping low-voltage or high voltage V2 is of about 1 second.As it has been described above, because provide pixel electrode 191h's and 191l The difference in voltage of common electrode 270 is arrived in voltage and offer, so forming electric field in liquid crystal layer 3.If forming electricity in liquid crystal layer 3 , then liquid crystal molecule 31 tilts along the direction that the longitudinal direction propping up 197h and 197l with differential is parallel, without forming electric field, Then liquid crystal molecule 31 is along the direction orientation vertical with upper display floater 100 or lower display floater 200.Because to pixel electrode The electric field conducting of the liquid crystal molecule 31 that 191h and 191l is alternately provided low-voltage and high voltage V2 is applied in liquid crystal layer 3 and Cut-off, so the most vertical orientated liquid crystal molecule 31 can be orientated along desired incline direction equably.
Subsequently, provide in the period at " TB2 " and little by little rise to the voltage of high voltage V2 from low-voltage, thus liquid crystal molecule 31 Sequentially it is orientated." TB2 " period can be about 1 second to about 100 seconds, be more preferably of about 30 seconds.Because when " TB2 " Duan Zhong, liquid crystal molecule 31 elapses over time when vertical orientated and props up 197 sequentially along the differential with pixel electrode 191 The parallel direction of longitudinal direction topple over (or inclination), can occur so preventing when forming burst electric field in liquid crystal layer 3 The irregular movement of liquid crystal molecule 31.
At next " TC2 " in the period, the longitudinal direction that liquid crystal molecule 31 props up 197 along the differential with pixel electrode 191 is put down The direction of row tilts, and then makes the layout stabilisation of liquid crystal molecule 31." TC2 " period is of about 1 second to about 600 seconds, more It is preferably about 40 seconds.At " TC2 " during the period, provide high voltage V2 constantly.
Then, " TD2 " of light is being irradiated to LCD board component 300 in the period, it is provided that predetermined exposure voltage, by This liquid crystal molecule 31 is orientated at steady state, performs field exposure technology at " TD2 " during the period." TD2 " period is of about 80 Second, to about 200 seconds, is more preferably of about 150 seconds.Exposure voltage can be identical with the final voltage of the second voltage.Exposure electricity Pressure is of about 5V to about 60V, is more preferably of about 30V to about 50V.In an exemplary embodiment of the present invention, if The thickness of liquid crystal layer 3 is of about 3.6 μm, then exposure voltage can be about 20V to about 40V, if the thickness of liquid crystal layer 3 is About 3.2 μm, then exposure voltage can be about 10V to about 30V.
In the optional exemplary embodiment of the present invention, ground voltage or big can be provided to pixel electrode 191h and 191l The voltage of about 0V, can provide predetermined the second voltage (0V and V2) to common electrode 270.
In next step S154, upwards display floater 200 and lower display floater 100 provide DC or multilevel voltage, so After in liquid crystal layer 3, form predetermined electric field while, such as during TD1 or the TD2 period, to liquid crystal layer 3 or have table Lower display floater 100 or the upper display floater 200 of planar orientation reactant irradiate light, ultimately form photo-hardening layer.About to liquid crystal The light that layer 3 irradiates, it can irradiate along lower substrate 110 and any one direction of upper substrate 210 or both direction.More preferably Ground, in order to reduce unhardened photo-hardening agent and be formed uniformly photo-hardening layer, light can be along the substrate of lower display floater 100 110 and upper display floater 200 substrate 210 in the direction of any one substrate with the less layer absorbing or stopping light Incident.
Now, will be described in (such as exposing work by field by the technique irradiating light to the liquid crystal layer 3 being formed with electric field Skill) method that forms lower plate photo-hardening layer 35.Liquid crystal layer 3 is deposited in the case of electric fields, near the liquid of main oriented layer 33 Brilliant molecule 31 is oriented to prop up the direction of 197 with differential and tilts abreast.With the inclination with the liquid crystal molecule 31 in main oriented layer 33 The substantially the same angle of inclination of angle makes the photo-hardening agent being present in liquid crystal layer 3 harden by the light irradiated, and is therefore formed Photo-hardening layer 35.Photo-hardening layer 35 is formed in main oriented layer 33.After removal is formed at the electric field in liquid crystal layer 3, light is hard The side chain polymer of change layer 35 keeps original directivity of adjacent liquid crystal molecule 31.According to an exemplary embodiment of the present invention Liquid crystal cell is photo-hardening agent, it is possible to the anisotropy by UV or by induction liquid crystal cell keeps adjacent at a certain temperature Original directivity of liquid crystal molecule 31.
It is described above " TD1 " or " TD2 " period.To liquid crystal layer 3 irradiate light can be collimation UV, polarization UV or Unpolarized UV.UV wavelength can be about 300nm to about 400nm.Luminous energy is of about 0.5J/cm2To about 40J/cm2, more excellent Selection of land is of about 5J/cm2.The light and the light cured the sealant that make photo-hardening agent harden can be not in terms of wavelength and energy With.
So, if liquid crystal molecule 31 is parallel along the longitudinal direction propping up 197 with differential by the polymer of photo-hardening layer 35 Direction keep pre-tilting angle, then when formed electric field so that liquid crystal molecule 31 direction change time, liquid crystal molecule 31 is rapidly Tilt, it is ensured that the fast response time (RT) of liquid crystal indicator.Liquid crystal molecule 31 phase near the side chain of photo-hardening layer 35 Vertical direction for lower display floater 100 has the most constant pre-tilting angle, but when liquid crystal molecule 31 is from photo-hardening When layer 35 moves the center to liquid crystal layer 3, liquid crystal molecule 31 may not have constant pre-tilting angle.In order to improve liquid crystal The contrast of showing device also prevents the light under without electric field status from leaking, and is adjacent to the liquid crystal molecule 31 of photo-hardening layer 35 not With, the liquid crystal molecule 31 of the center of liquid crystal layer 3 can not have pre-tilting angle.
In an exemplary embodiment of the present invention, because the unhardened photo-hardening agent stayed in liquid crystal layer 3 can cause remaining Picture or image viscous, so in order to remove the unhardened photo-hardening agent being present in liquid crystal layer 3 or in order to make there is pre-dumping The photo-hardening layer 35 and 36 of rake angle is stable, in the case of not having electric field to be formed in liquid crystal layer 3, can perform to liquid crystal layer 3 techniques irradiating light, such as fluorescence exposure technology.According to the exemplary embodiment of the present invention, in fluorescence exposure technology, light can With irradiate about 20 minutes to about 80 minutes, be more preferably of about 40 minutes.The light irradiated can be that wavelength is of about The UV of 300nm to about 390nm, the illuminance of the light of irradiation can be about 0.05mW/cm under the wavelength of 310nm2To greatly About 0.4mW/cm2。
In an alternative illustrative embodiment, lower plate photo-hardening layer 35 or upper plate photo-hardening layer 36 can be formed, based on shape The intensity of electric field in liquid crystal layer 3, the level of pixel voltage, the time of voltage to pixel PX provides, luminous energy, light is become to irradiate Amount, light irradiation time or combinations thereof, lower plate photo-hardening layer 35 or upper plate photo-hardening layer 36 have various pre-tilting angle Side chain.In the exemplary embodiment, when the exposure voltage different to pixel electrode 191h with 191l offer, have The first sub-pixel 190h and the second sub-pixel 190l of the photo-hardening layer 35 and 36 of different pre-tilting angle can be exposed by field Technique is formed.In a further exemplary embodiment, different exposure voltages can be applied according to pixel or apply different fields to expose Light technique so that the photo-hardening of at least one pixel (such as, blue pixel) in the primary color pixels of composition base pixel group PS Layer can have different pre-tilting angle from the photo-hardening layer of other pixel.
It is attached to polariser (not shown) hold display floater 100 and upper display floater 200 by sealant group.Institute The LCD board component 300 with the photo-hardening agent being included in liquid crystal layer 3 assembled has the characteristic of SVA pattern.

After post bake, surface orientation reactant 10 cleans with DIW, it is possible to clean with IPA further.Cleaning Afterwards, surface orientation reactant 10 is dried.
In step S240, between lower display floater 100 and upper display floater 200, form upper plate common voltage apply point (not shown), sealant and liquid crystal layer 3, wherein, be formed with surface light hardening oxidant layer 35a and main orientation on each display floater Layer 33, then assembles display floater 100 and 200.After drying, lower display floater 100 forms sealant.In order to improve Adhere to, sealant can be formed on the perimeter not forming surface orientation reactant 10 of lower display floater 100.The opposing party Face, the mode partly can being stacked with surface orientation reactant 10 according to sealant, lower display floater 100 or on aobvious Show formation sealant on the perimeter of panel 200.Sealant can comprise light trigger, and described light trigger by wavelength is About 300nm hardens to the UV of about 400nm.Under wavelength is of about 300nm to about 400nm, the light trigger of hardening can Think Benzyl Dimethyl Ketal (benzil dimethyl ketal) (BDK, Irgacure-651) or above-mentioned light trigger In one.
After drying, upper display floater 200 forms upper plate common voltage and apply some (not shown) and liquid crystal layer 3.On Plate common voltage applies point and receives common voltage Vcom provided from outside (such as, data driver 500), and common voltage Vcom is carried It is fed to the common electrode 270 being formed on display floater 200.Upper plate common voltage applying point can directly contact and be formed at lower display Common voltage on panel 100 applies pattern (not shown) and the common electrode 270 being formed on display floater 200.Common voltage is executed Add pattern and be connected to data driver 500 to receive common voltage Vcom, it is possible to formed altogether while forming pixel electrode layer Voltage applies pattern.Upper plate can be formed on the perimeter not forming surface orientation reactant 10 of upper display floater 200 Common voltage applies point.Upper plate common voltage applies point can include the spheric conductor of conduction and a diameter of about 4 μm or less.? Form liquid crystal layer 3 in formation on the region of the surface orientation reactant 10 of display floater 200, or form the region of sealant Be internally formed liquid crystal layer 3.Can perform to form upper plate common voltage simultaneously and apply point and the technique of liquid crystal layer 3.According to the present invention Another exemplary embodiment, by by sealant (such as, conductive seal agent) with formed upper plate common voltage apply point conductor Mixing, sealant and upper plate common voltage apply point and can be formed from the same material in single technique.At lower display floater 100 Formed conductive seal agent region in, the pattern of data Layer conductor can not be formed in the lower floor of conductive seal agent, thus Prevent the pattern short circuit of conductive seal agent and data Layer conductor.
After forming sealant and liquid crystal layer 3, assemble lower display floater 100 and upper aobvious by sealant in a vacuum chamber Show panel 200.
In step s 250, when exposure voltage being provided to the display floater 100 and 200 assembled, then irradiate to it Light time (such as, when the display floater 100 and 200 assembled experiences field exposure technology), the main oriented layer of lower plate 33 is formed Lower plate photo-hardening layer 35, and in the main oriented layer of upper plate 34, form upper plate photo-hardening layer 36.Main oriented layer 33 and 34 is hard with light Change layer 35 and 36 and respectively constitute alignment films 291 and 292.
After assembling, make sealant be exposed to wavelength and be of about the UV of 300nm to about 400nm, or be exposed to ripple The long visible ray being of about 400nm or bigger, has thus been hardened about 80%.UV or visible ray can be by from lower display surfaces The external incident of plate 100 is irradiated to sealant.Radome is between sealant and UV source, and shields UV so that UV will not Irradiate the region in addition to sealant.If the UV being irradiated to sealant makes the light around sealant hard because of its deviation Agent is hardened, then because the photo-hardening agent around sealant is hardened, in advance so liquid crystal indicator can be in the week of sealant Enclose and there is edge smudge defect.Photo-hardening agent around sealant can be to form the photo-hardening agent of alignment films or be present in liquid Photo-hardening agent in crystal layer 3.In the case of there is no radome, it is seen that light can be irradiated to sealant.
Then, sealant experiences heat cure about 70 minutes at about 100 DEG C.
After assembling, in order to improve ambiguity and the uniformity of liquid crystal molecule 31, by lower display floater 100 and upper display Panel 200 is annealed about 60 minutes to about 80 minutes in the room of about 100 DEG C to about 120 DEG C.
Because providing exposure voltage to the display floater 100 and 200 assembled after anneal and forming electricity in liquid crystal layer 3 The technique (step S252) of field is substantially the same with step S152 of manufacture method based on SVA pattern, retouches so eliminating it State.
In next step S254, describe while forming electric field by the LCD board component assembled The technique that the 300 field exposure technologys irradiating light form photo-hardening layer 35.Because irradiating light then photo-hardening in step S254 The technique that layer 35 makes liquid crystal molecule 31 be orientated is identical with step S154 in SVA pattern, describes in detail so eliminating it.In order to Reduce unhardened photo-hardening agent and be formed uniformly photo-hardening layer, be irradiated to surface light hardening oxidant layer 35a light can along under The less layer that having in the substrate 110 of display floater 100 and the substrate 210 of upper display floater 200 absorbs or stop light The direction of any one substrate is incident.
Now, will be described in detail in when receiving light with reference to Fig. 9 A and Fig. 9 B, be formed at the surface light in main oriented layer 33 The technique that hardening oxidant layer 35a becomes photo-hardening layer 35.
If forming electric field in liquid crystal layer 3, then the surface light sclerosing agent 43 of surface light hardening oxidant layer 35a is along with adjacent The direction that the differently-oriented directivity of liquid crystal molecule 31 is substantially the same is orientated, and surface light sclerosing agent 43 passes through incident UV along with adjacent The substantially the same direction hardening in the direction of liquid crystal molecule 31.That be orientated and hardening surface light sclerosing agent 43 forms photo-hardening Layer 35, thus adjacent with photo-hardening layer 35 liquid crystal molecule 31 has pre-tilting angle.Surface light as shown in fig. 9 a and fig. 9b Sclerosing agent 43 is to constitute the vertical orientated monomer 41 of the main oriented material in surface and include that the monomer chemistries of reactive mesogen combines Macromolecular compound.When irradiating UV, have the surface light sclerosing agent 43 of reactive mesogen have by UV untie double Key, and it is additionally formed side chain network 40.By such reaction, it is hard that surface light sclerosing agent 43 forms light by UV irradiation hardening Change layer 35.Therefore, the photo-hardening layer 35 along the direction orientation being slightly slanted relative to the normal orientation of lower substrate 110 is formed at and makes In the main oriented layer 33 that liquid crystal molecule 31 is vertical orientated.In order to make unhardened photo-hardening agent harden and make photo-hardening layer 35 steady Fixed, fluorescence exposure technology described above can be performed.
As described by above in conjunction with SVA pattern, because photo-hardening layer 35 is taking along the incline direction of liquid crystal molecule 31 Harden while to, so, even if not in the case of liquid crystal layer 3 applies electric field, liquid crystal molecule 31 still have along with The differential of pixel electrode 191 props up the pre-tilting angle of the parallel incline direction of longitudinal direction of 197.
The LCD board component 300 assembled by this way has the characteristic of SC-VA pattern.If according to SC-VA Pattern manufactures liquid crystal indicator, then photo-hardening agent is present in and is not present in liquid crystal layer 3, significantly around main oriented layer 33 Decrease the unhardened photo-hardening agent staying in liquid crystal layer 3.Therefore, there is the liquid crystal indicator of the characteristic of SC-VA pattern Improve image viscous defect, it is ensured that good quality.Furthermore it is possible to be omitted in without irradiating light under the state of electric field so that not The technique of the photo-hardening agent hardening of hardening, reduces the manufacturing cost of liquid crystal indicator.
Now, the liquid crystal indicator that manufactures based on SC-VA pattern will be described in detail with reference to Figure 10 and table 2 and table 3 Characteristic.Table 2 shows that liquid crystal indicator based on SC-VA pattern is relative to the surface being included in surface orientation reactant 10 The characteristic of the ratio of components change of main oriented material and surface light sclerosing agent.The composition surface main orientation material used in these experiments The alicyclic dianhydride class monomer of material, aromatic diamine class monomer, alicyclic cyclosubstituted aromatic diamine class monomer and aromatic ring oxidation Species monomer is respectively thricyclohexyl dianhydride, terphenyl diamidogen, cholesteryl phenylenediamine and six epoxy benzene derivatives.It addition, The alicyclic dianhydride class monomer of the composition surface light sclerosing agent used in these experiments, photoreactivity two anhydride monomer, alkyl The aromatic diamine class monomer changed and aromatic diamine class monomer are respectively thricyclohexyl dianhydride, monomethacrylate phenylenediamine, single alkane The phenylcyclohexyl phenylenediamine of base and six epoxy benzene derivatives.
The structure of pixel PX is substantially the same with the structure that figure 3 illustrates.The differential of pixel electrode 191 props up the width of 197 Degree is of about 3 μm, and the box in liquid crystal layer 3 is spaced apart about 3.6 μm.Exposure voltage is of about 7.5V, the UV intensity in the exposure of field It is of about 5J/cm2.Liquid crystal indicator is by 1 gate line 1 data wire shared based on electric charge described below in conjunction with Figure 11 (1G1D) driving runs.Other condition is identical with the condition being applied to liquid crystal indicator based on SC-VA pattern.

As shown in figure 12, basic pixel group PS is by corresponding pixel electrode 191R, 191G and the 191B of the primary colors of red, green, blue Composition.The pixel electrode 191G of the pixel electrode 191R and green pixel PX of red pixel PX is the most identical, but blue The pixel electrode 191B of pixel PX is different from other pixel electrodes 191R and 191G structurally part.Basic pixel group PS by with Redness, green and the blue pixel PX composition that three primary colors (red R, green G and blue B) is corresponding.Redness, green and blue pixel PX is respectively provided with redness, green and blue pixel electrode 191R, 191G and 191B.The color filter presenting primary colors may be formed at lower aobvious Show on panel 100 or upper display floater 200.Pixel electrode 191R, 191G and 191B are each divided into being formed at two sub-pixels Two pixel electrode 191h and 191l in region.Red pixel electrode 191R has the first sub-picture being formed at red pixel The first red sub-pixel electrode 191hR in element region is red with second be formed in the second subpixel area of red pixel Pixel electrode 191lR.It is first green that green pixel electrode 191G has in the first subpixel area being formed at green pixel Sub-pixels electrode 191hG and the second green sub-pixels electrode 191lG being formed in the second subpixel area of green pixel. Blue pixel electrode 191B has the first blue subpixels electrode 191hB in the first subpixel area being formed at blue pixel With the second blue subpixels electrode 191lB in the second subpixel area being formed at blue pixel.First red sub-pixel electricity Each differential Zhi Kuandu and micro chink width in pole 191hR and the first green sub-pixels electrode 191hG are respectively about 3 μm About 3 μm, differential Zhi Kuandu and the micro chink width of the first blue subpixels electrode 191hB are respectively about 3 μm and about 4 μm.In second red sub-pixel electrode 191lR, the second green sub-pixels electrode 191lG and the second blue subpixels electrode 191lB Each differential Zhi Kuandu and micro chink width be respectively about 3 μm and about 3 μm.Exemplary enforcement according to the present invention Example, the first pixel electrode in other pixels of width ratio of the micro chink of the first pixel electrode 191hB in blue pixel The width of the micro chink of 191hR and 191hG and second pixel electrode 191lR, 191lG and 191lB is big, thus reduces indigo plant The brightness of the first sub-pixel in color pixel.
First red sub-pixel electrode 191hR, the first green sub-pixels electrode 191hG and the first blue subpixels electrode The direction that each differential in 191hB props up is the θ 3 of about 40 °.Second red sub-pixel electrode 191lR, the second green sub-picture The direction that each differential in element electrode 191lG and the second blue subpixels electrode 191lB props up is the θ 4 of about 45 °.θ 3 and θ 4 angles being the polarization axle relative to polariser.If in this manner by first pixel electrode 191hR, 191hG and The direction that micro-branch direction of 191hB and the differential of second pixel electrode 191lR, 191lG and 191lB prop up arranges different, Then have adjusted brightness and the brightness of the second sub-pixel of the first sub-pixel.In each pixel of formation base pixel groups, second The area of sub-pixel is about 1.75 times of the area of the first sub-pixel.
Now, will be described with the light of the liquid crystal indicator of the pixel electrode 191 of basic pixel group PS shown in Figure 12 Learn characteristic and effect.Figure 13 A is the curve chart of the gray-scale intensity ratio measured in traditional liquid crystal indicator, at traditional liquid In crystal device, all pixel electrodes of formation base pixel groups PS have identical structure.Figure 13 B is to have according to this Invention exemplary embodiment in the liquid crystal indicator of the pixel electrode 191 of basic pixel group PS shown in Figure 12 measure The curve chart of gray-scale intensity ratio.Liquid crystal indicator based on SVA pattern manufacture and utilizes according to an exemplary embodiment of the present invention 1G1D based on CS charging drives and operates.Additionally, in the present example embodiment of the present invention, in the second pixel electrode The voltage being filled with is about 0.77 times of the voltage being filled with in the first pixel electrode, and the box interval (cell in liquid crystal layer Spacing) it is about 3.55 μm.
Gray-scale intensity represents the ash corresponding with providing the voltage of pixel electrode 191h and 191l than the transverse axis of curve chart Rank, its longitudinal axis represents the brightness ratio of liquid crystal indicator, described brightness ratio on the right side of liquid crystal indicator at about 60 ° by point Light microscopic records.The brightness ratio of the longitudinal axis recorded at about 60 ° of right side represents the gray-scale intensity high-high brightness with each color Ratio.Come with reference to the blue luminences curve B1 shown in Figure 13 A by way of example, if the brightness of blue pixel is at the highest ash Rank 250 are 100 candelas (cd), are 50cd at GTG 150, then the brightness ratio of blue luminences curve B1 is about 0.5.Figure 13 A Shown curve R1, G1, B1 and W1 is HONGGUANG, green glow, blue light and the white light measured in traditional liquid crystal indicator respectively Brightness ratio curve.Curve R2, G2, B2 and W2 shown in Figure 13 B is at liquid crystal according to an exemplary embodiment of the present invention respectively The brightness ratio curve of HONGGUANG, green glow, blue light and the white light measured in display device.White brightness W1 is HONGGUANG brightness R1, green glow Brightness G1 and blue light brightness B1 sum, white brightness W2 is HONGGUANG brightness R2, green glow brightness G2 and blue light brightness B2 sum. The ratio of HONGGUANG brightness, green glow brightness and blue light brightness and white brightness is respectively about 55% to about 65%, 20% to about 30% and 10% to about 20%.
As can be from the curve chart finding of Figure 13 A, in the middle of being represented by ellipse in ash exponent part A8, traditional HONGGUANG be bright The degree slope than curve R1 increases suddenly and intersects than curve B1 with blue light brightness.Have passed through HONGGUANG brightness ratio curve R1 with blue After the point that brightness intersects each other than curve B1, HONGGUANG brightness ratio is more than blue light brightness ratio.Become little at this blue light brightness ratio In the grey exponent part A8 of HONGGUANG brightness ratio, general yellow occurs in the side of liquid crystal indicator.If visually observed To general yellow, then image quality reduces and the color of original image is mixed and disorderly (disordered), thus makes liquid crystal display fill The display quality deterioration put.It is therefore prevented that it can be favourable that general yellow is visually aware.The brightness ratio of primary colors Intersected with each other at a specific GTG of high gray, but the luminance difference between high gray, GTG is big, so seeing hardly Observe fragmentary general yellow.
But, as shown in Figure 13 B, there is the pixel electrode of basic pixel group PS according to an exemplary embodiment of the present invention The HONGGUANG brightness ratio curve R1 that liquid crystal indicator is not observed in traditional liquid crystal indicator and blue light brightness are than song The point that line B1 is intersected with each other.In the middle ash exponent part A8 represented by ellipse in Figure 13 B, due to HONGGUANG brightness ratio curve R2 and blue light brightness than curve B2 on slope similar, so there is no HONGGUANG brightness ratio and blue light brightness than point intersected with each other. Therefore, liquid crystal indicator does not produce general yellow according to an exemplary embodiment of the present invention.
Additionally, if owing to the brightness ratio of different primary colors is certain GTG is intersected with each other, brightness ratio of in primary colors becomes Change, then liquid crystal indicator can cause chromatic error or colo(u)rimetric shift.In order to this is corrected, can evenly structure basis Brightness ratio in the primary color pixels of pixel groups.
