The present inventor has found during practical study, current liquid crystal display panel in the preparation, light orientation
During using ultraviolet light irradiation control liquid crystal alignment, the alignment film of formation make liquid crystal molecule have specific pre-dumping
Angle, however in existing liquid crystal display demand, with the display panel of pre-tilt angle, transmitance and display in current orientation
Effect etc. still needs to further be promoted, and such as alignment film keeps the pre-tilt angle of liquid crystal generally higher in existing smooth alignment method, causes
View field of the liquid crystal molecule on light direction is smaller, therefore can not change the polarization direction of more light, thus can not
Guarantee that more light can adapt to the polarization direction of polaroid of liquid crystal display panel light emission side, reduce liquid crystal display panel
Light transmission rate causes its display effect poor.
And, the embodiment of the present invention provides following solution based on above-mentioned discovery:
Referring to figs. 1 to shown in Fig. 6, the embodiment of the present invention provides a kind of liquid crystal display panel 100, comprising:
To the first substrate 10 and the second substrate 20 of box setting, and it is folded between first substrate 10 and the second substrate 20
Layer of liquid crystal molecule 30.
The first both alignment layers 40 and second that light orientation is respectively formed on first substrate 10 and the inner surface of the second substrate 20 are matched
To layer 50, the first both alignment layers 40 and the second both alignment layers 50 can drive liquid in the case where having the orientation light irradiation of default incident angle
The multiple liquid crystal molecules 31 of brilliant molecular layer 30 form the orientation of pre-tilt angle, and the range of pre-tilt angle is between 88.9 ° to 89.5 °.It needs
It is noted that in the present embodiment, the inner surface of first substrate 10 and the second substrate 20 refers to first substrate 10 and the second substrate
20 towards the side of layer of liquid crystal molecule 30, for the display effect for further increasing display panel, in the pre-dumping of adjustment liquid crystal molecule
The influence of distributing position for when angle, needing the variation for considering pre-tilt angle simultaneously to transmitance, displaying contrast and forming dark line,
Quality is shown with effective promotion.In the present embodiment, liquid crystal molecule 31 is made to form 88.9 ° to 89.5 ° of pre-tilt angle of orientation,
The display panel formed at this time has preferable transmitance and contrast, and smaller on the influence of dark line width distribution, has preferable
Display effect.Specifically, in the present embodiment, respectively with regard to the numerical value of pre-tilt angle to transmitance, display contrast and show
The influence of the distributing position of region dark line is studied, wherein the pre-tilt angle of different degrees is to liquid crystal molecule light transmission rate
It influences as shown in figs. 2 a and 2b, by Fig. 2 a and 2b it is found that in two kinds of orientation agent of AL418NK and PPA-2108-R1, with liquid
The increase of brilliant molecule pre-tilt angle, transmitance gradually increase, however when the transmitance of liquid crystal molecule is 90 °, transmitance
Minimum, therefore, under the premise of guaranteeing permeability, when making the orientation of 88.9 ° to 89.5 ° of pre-tilt angle of liquid crystal molecule formation, i.e.,
It can transmitance with higher.
Wherein, polymer continue orientation (Polymer Sustained Alignment, PSA) alignment mode and
Under the alignment mode of UV2A, influence of the different numerical value pre-tilt angles to the contrast of display panel is as shown in Figure 3, from the figure 3, it may be seen that
Under PSA alignment mode and UV2A alignment mode, by adjusting orientation angle of light, make the first both alignment layers 40 and the second orientation
Layer 50 drives liquid crystal molecule in layer of liquid crystal molecule 30 to form pre-tilt angle when being 85 ° to 90 °, with the increase of pre-tilt angle numerical value,
Its contrast is gradually increased, and when pre-tilt angle is greater than 88.9 °, contrast tends to be steady substantially, i.e., liquid crystal molecule formation pre-tilt angle is
When orientation greater than 88.9 °, liquid crystal display panel has preferably contrast, helps to promote display effect, in addition, in UV2A
Under alignment mode, the contrast of liquid crystal display panel is generally higher than the liquid crystal display panel obtained under PSA alignment mode.
Wherein, under the alignment mode of UV2A, influence of the different numerical value pre-tilt angles to the dark line distributing position of display area
As shown in Figure 4, when the dark line distributing position of formation is remoter away from pixel electrode edge, the width of concealed wire just be will increase, from
And aperture opening ratio is influenced, the display effect of display panel is reduced, as shown in Figure 4, with the increase of pre-tilt angle numerical value, the distribution of dark line
Position is remoter away from (25mm is at electrode edge position) at pixel electrode marginal position, and the influence to aperture opening ratio is bigger.
Therefore, in conjunction with Fig. 2 a, 2b, Fig. 3 and Fig. 4, comprehensive pre-tilt angle to transmitance, the concealed wire that displays contrast and formed
Distributing position considers, is 88.9 ° to 89.5 ° when driving the liquid crystal molecule in layer of liquid crystal molecule to form pre-tilt angle, the display of acquisition
Panel has preferably display quality and display effect, even if the first both alignment layers 40 and the second both alignment layers 50 have default incidence
Under the orientation light irradiation of angle, the multiple liquid crystal molecules 31 of layer of liquid crystal molecule 30 is driven to form the orientation of pre-tilt angle, and pre-tilt angle
Range between 88.9 ° to 89.5 °, can effectively improve transmitance, promotion displays contrast, and to the width of dark line point
Cloth influence is smaller, can be obviously improved display panel display effect and display quality.
Further, in the present embodiment, pre-tilt angle is greater than or equal to 89.0 °.It should be pointed out that improve display surface
The display effect of plate also needs to consider liquid crystal molecule pre-dumping while adjusting liquid crystal molecule pre-tilt angle degree to adjust transmitance
Influence of the angle number to distribution, the contrast of concealed wire etc., in conjunction with these parameters, based on the description above process it is found that working as liquid crystal
For the numerical value of the pre-tilt angle of molecule at 89.0 °, display panel has preferable transmitance, higher contrast and lesser dark
Schlieren is rung, and therefore, the present embodiment can also further limit, pre-tilt angle is big in the range of pre-tilt angle is 88.9 ° to 89.5 °
In or equal to 89.0 °.

Shown, the default incident angle of orientation light is the incident direction L2 of orientation light and the normal side of the first both alignment layers or the second both alignment layers
To the angle of L1, the first both alignment layers 40 and the second both alignment layers 50 in the case where orientation light of the default incidence angle for 0 ° and 60 ° between irradiates,
Alignment effect of the liquid crystal molecule 31 by the first both alignment layers 40 and the second both alignment layers 50, can be formed pre-tilt angle be 88.9 ° extremely
Orientation between 89.5 °.
Further, in the present embodiment, the default incident angle of orientation light is less than or equal to 40 °, in the present embodiment,
Table 1 is the pre-tilt angle of the liquid crystal molecule in the case where different alignment light presets the irradiation of incidence angle light, AL418NK and two kinds of PPA-2108-R1
The pre-tilt angle numerical value that orientation agent drives liquid crystal molecule to be formed, as shown in Table 1, with the increase of default incidence angle, liquid crystal molecule shape
At pre-tilt angle numerical value reduce, and by above-mentioned discussion it is found that when pre-tilt angle numerical value reduces its transmitance and contrast and can subtract
Small, dark line width increases, and is unfavorable for display effect, therefore, in the present embodiment, further limits the default incidence of orientation light
Angle is less than or equal to 40 °, so that display panel has better display effect.
