It should be noted that the display panel that various embodiments of the present invention provide is applied to one-domain structure, double domain structures, its
In, double domain structures include very double domain structures and pseudo- double domain structures.
First, one-domain structure is briefly described.In some optional embodiments, carried in any embodiment of the present invention
On the basis of the display panel of confession, gate line extends along line direction, and data wire extends along column direction；Main part prolongs along column direction
Stretch, any in the bearing of trend of corner part, line direction, column direction the two is intersecting.Below, only by taking Figure 11 as an example, to single domain knot
Structure illustrates.Figure 11 has continued to use Fig. 3 reference, and Figure 11 illustrates a kind of display panel of middle-com structures, its
In, pixel electrode 31 includes a strip shaped electric poles portion 50.Gate line 10 extends along line direction, and data wire 20 extends along column direction；

In the display panel that example provides, in each pixel electrode 31, the bearing of trend of main part 51 is identical, specifically, 51 equal edge of main part
Column direction extends.In display panel, the orientation of the liquid crystal molecule in liquid crystal layer is related to the bearing of trend of main part 51, due to
The bearing of trend of main part 51 in each pixel electrode 31 is identical, therefore can set the equally oriented of liquid crystal molecule, this knot
Structure is one-domain structure.
Then, double domain structures are briefly described.The visual angle of liquid crystal display panel has anisotropic weakness, and this is
Because liquid crystal molecule is that approximation is cylindric, has major axis and short axle, the yawing moment difference of liquid crystal molecule, pass through LCD
The optical path difference of the light of plate is different, thus causes the visual angle of liquid crystal display panel to have anisotropic phenomenon.Double domain structures
Principle is, by the middle setting Liang Zhongchou areas of display panel, respectively farmland area A and farmland area B, farmland area A and farmland area B liquid crystal point
Son orientation contrast, can so solve the viewing angle problem in horizontally or vertically direction.Very double domain structures refer to, farmland area A and
Farmland area B is located in same subpixel area；Pseudo- double domain structures refer to that farmland area A and farmland area B are located at two adjacent sub- pictures respectively
In plain region.Very double domain structures and pseudo- double domain structures can increase the visual angle of liquid crystal display panel, improve the color of display panel
Inclined problem.
