Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Whole description, described embodiment are part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
Refering to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of the embodiment of display panel one provided by the invention, and Fig. 2 is this hair
The cross-sectional structure schematic diagram of the embodiment of display panel one of bright offer, the liquid crystal display panel 10 include multiple pixels 12, often
Liquid crystal layer 126 between the individual upper substrate 122 of pixel 12, infrabasal plate 124 and upper substrate 122 and infrabasal plate 124.
Optionally, colored filter can be set on the glass of upper substrate 122, TFT is set on the glass of infrabasal plate 124
(thin film transistor (TFT)), changed by the signal on TFT and voltage to control the rotation direction of liquid crystal molecule in liquid crystal layer 126, from
And reach each pixel polarised light of control and whether be emitted and reach display purpose.
Specifically, infrabasal plate 124 can specifically include the glass substrate being stacked, grid, gate insulator, semiconductor
Layer, flatness layer, source-drain layer and pixel electrode layer, upper substrate 122 can specifically include color filter layers and public electrode
Layer.Certainly, in other embodiments, color filter layers and common electrode layer can also be arranged on infrabasal plate 124.In addition,
When the display panel is flexible display panels, glass substrate therein can also be flexible plastic base.
(it is not powered on pressing) when static, liquid crystal molecule vertical arrangement；When adding a voltage on liquid crystal, molecule will hang down again
In line row, under outside electric field action, induced dipoles are produced in liquid crystal molecule, then induced dipoles are driven by external electrical field
It is dynamic, liquid crystal molecule is deflected.
Wherein, as shown in Fig. 2 each pixel 12 includes first area 21 and second area 22.Wherein liquid crystal layer 126
There is the first pre-tilt angle in corresponding first area 21, liquid crystal layer 126 has the second pre-tilt angle in correspondence second area 22, and described the
One pre-tilt angle and second pre-tilt angle are unequal.
It should be understood that because VA shows the internal factor of liquid crystal, when the pre-tilt angle of all liquid crystal molecules is identical, not
With position it was observed that image can have differences all the time.This may result in the image observed in the case of big visual angle with facing
When the image observed it is different, here it is big visual angle colour cast problem；Basic reason is horizontal liquid crystal molecule when facing,
Look like during big visual angle oblique；Oblique liquid crystal molecule when facing, looks like horizontal at big visual angle, and this can cause big visual angle
The image serious distortion seen.
And in the present embodiment, there are two kinds of different pre-tilt angles by making the liquid crystal molecule in same pixel so that
For user in two different angle viewings, it is same pre-tilt angle for user perspective always to have partial liquid crystal molecule.
For example, such as in a pixel pre-tilt angle of liquid crystal molecule corresponding to first area 21 is 3 °, when user's
When sight is perpendicular to display panel, liquid crystal molecule is 3 ° relative to the angle of inclination of sight.When the sight and display panel of user
Angle be less than 90 ° when, i.e., user not display panel centre viewing when, liquid crystal molecule is with regarding corresponding to first area 21
Angle between line is not then 3 °, and colour cast now occurs.And liquid crystal molecule corresponding to second area 22 is not due to pre-tilt angle
3 °, for example, can be 10 °, when now user is watched by second area 22, liquid crystal molecule and sight corresponding to second area 22
Between angle compared to first area 21 for, desired angle is more nearly, it is thereby possible to reduce colour cast.
Prior art is different from, the display panel that the present embodiment provides includes multiple pixels, and each pixel includes the firstth area
Domain and second area；Liquid crystal layer has the first pre-tilt angle in corresponding first area, and liquid crystal layer has second in corresponding second area
Pre-tilt angle, the first pre-tilt angle and the second pre-tilt angle are unequal.By the above-mentioned means, can by changing liquid crystal molecule pre-tilt angle,
So that the liquid crystal molecule in a pixel has two kinds of different pre-tilt angles, user is set to be seen when different angle is watched
To the colored picture close to ideal situation, colour cast is effectively reduced, improves display quality.
It should be understood that in the above-described embodiments, liquid crystal layer only is divided into two regions, make two regions corresponding
Liquid crystal molecule pre-tilt angle it is different.In other embodiments, three, four ... different regions can also be divided into, are made
The pre-tilt angle of liquid crystal molecule is different corresponding to each region.For example, the pre-dumping of the liquid crystal molecule in continuous multiple regions can be made
Angle is incremented by successively, and its principle is similar to the above embodiments, will not enumerate here.
Refering to Fig. 3, Fig. 3 is the structural representation of another embodiment of display panel provided by the invention, different from above-mentioned reality
Apply example, each pixel in the present embodiment includes first area 21, second area 22 and for being spaced first area and second
3rd region 23 in region.
Wherein, liquid crystal layer 126 does not have pre-tilt angle in corresponding 3rd region 23.
It should be understood that because first area 21 is different with the pre-tilt angle of the liquid crystal molecule of second area 22, to liquid crystal
Layer 126 applies in voltages, the liquid crystal molecule deflection of two region intersections may confusion reigned, influence display effect.Therefore,
In the present embodiment, one the 3rd region 23, liquid corresponding to the 3rd region 23 are increased between first area 21 and second area 22
Brilliant molecule is not provided with pre-tilt angle, so can effectively prevent the liquid crystal molecule deflection in two regions from causing confusion.

In the second pre-tilt angle.In other words, namely the first pixel electrode 41 area be less than the second pixel electrode 42 area.
It should be understood that when the liquid crystal molecule to liquid crystal layer 126 forms pre-tilt angle, the side of ultraviolet light can be used
Formula.As shown in figure 5, in order to which different zones in one pixel make liquid crystal molecule form different pre-tilt angles, can use not
It is irradiated with the light shield of light transmittance.
Specifically, the light transmittance of the first light shield 51 is more than the light transmittance of the second light shield 52, and the 3rd light shield 53 is light tight.Cause
This, is when blocking ultraviolet progress light orientation using three light shields, liquid corresponding to first area 21 corresponding to the first light shield 51
The pre-tilt angle of brilliant molecule is larger, and the pre-tilt angle of liquid crystal molecule corresponding to second area 22 corresponding to the second light shield 52 is smaller, and
