通常液晶显示装置包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组（Backlight module）。其中，液晶面板的结构主要是由一薄膜晶体管阵列基板（Thin Film Transistor Array
Substrate，TFT Array Substrate）、一彩色滤光片基板（Color Filter Substrate，CF Substrate）、以及配置于两基板间的液晶层（Liquid Crystal Layer） 所构成，其工作原理是通过在两片向TFT基板的像素电极和CF基板的公共电极上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。Generally, a liquid crystal display device includes a casing, a liquid crystal panel arranged in the casing, and a backlight module (Backlight module) arranged in the casing.

A driving voltage is applied to the pixel electrode of the pixel electrode and the common electrode of the CF substrate to control the rotation of the liquid crystal molecules of the liquid crystal layer, and refract the light from the backlight module to produce a picture.
为了液晶显示面板获得更好的广视角特性，改善色偏问题，现有技术提出了一种多畴技术，即将一个子像素划分成多个区域，并使每个区域中的液晶在施加电压后倒伏向不同的方向，从而使各个方向看到的效果趋于平均一致。如图1所示，现有采用多畴技术的像素电极结构包括条状的第一主干电极100、条状的第二主干电极200及多个条状的分支电极300；所述第一主干电极100和第二主干电极200垂直交叉划分出田字形分布的第一电极区域101、第二电极区域102、第三电极区域103及第四电极区域104，所述第一电极区域101、第二电极区域102、第三电极区域103及第四电极区域104内均设有平行间隔排列的多个分支电极300，每一个分支电极300的一端均与第一主干电极100和第二主干电极200中的一个相连，另一端均向远离所述第一主干电极100和第二主干电极200的交叉点的方向延伸；位于第二电极区域102内的分支电极300与位于第一电极区域101内的分支电极300关于第一主干电极100对称，位于第二电极区域102内的分支电极300与位于第三电极区域103内的分支电极300关于第二主干电极200对称，位于第四电极区域104内的分支电极300与位于第三电极区域103内的分支电极300关于第一主干电极100对称；每一个位于第三电极区域103内的分支电极300均与一个位于第一电极区域101内的分支电极300对应，且该位于第三电极区域103内的分支电极300靠近第二主干电极200的一侧边与该位于第三电极区域103内的分支电极300对应的位于第一电极区域101内的分支电极300靠近第一主干电极100的一侧边在同一直线上，也即位于第三电极区域103内的分支电极300与位于第一电极区域101内的分支电极300关于第一主干电极100和第二主干电极200的交叉点中心对称，位于第二电极区域102内的分支电极300与位于第四电极区域104内的分支电极300关于第一主干电极100和第二主干电极200的交叉点中心对称，由于液晶分子是连续体，多畴技术在改善视角的同时，也会在畴分界处及第一主干电极100和第二主干电极200的位置产生暗纹，并且在图1所示的像素电极结构中，在第一主干电极100和第二主干电极200交叉区域，由于偏转液晶长轴分子的连续态或局域电场影响，畴分界处的暗纹，该区域的暗纹难以控制，容易出现暗纹窜出进入开口区，影响面板的透过率和显示品质。In order to obtain better wide viewing angle characteristics of liquid crystal display panels and improve color shift, the prior art proposes a multi-domain technology, that is, a sub-pixel is divided into multiple regions, and the liquid crystal in each region is Lodging in different directions, so that the effects seen in all directions tend to be uniform.

When entering the opening area, it affects the transmittance and display quality of the panel.
