Description

一种像素结构及液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种像素结构及液晶显示面板。
 背景技术
VA（Vertical Alignment，垂直配向）液晶显示器中，薄膜晶体管侧的像素电极图形化，像素单元内液晶分子的长轴在不加电的状态下与滤光片垂直，每个像素单元被划分为多个畴区，在加电状态下，每个畴区内的液晶分子向各自的方向偏转，通过这种方法，将同一像素单元中的液晶分子取向分为多个方向，由此补偿各个角度的视角，进而实现各个视角方向的均匀显示，以有效改善不同观察角度的灰阶显示状态下的视角特性，防止产生色偏。
目前，VA 模式由于在不同视野角下，液晶分子双折射率的差异比较大，为了进一步改善色偏，行业内将像素电极由4畴区架构，转变成8畴区架构，使同一个子像素内分为4个主畴区和4个副畴区，通过多颗薄膜晶体管（一般为3颗）的作用，使得主畴区与副畴区具有不同的电压差，达到改善色偏的效果。
然而，由于副畴区亮度非最大值，从而造成整体穿透率显著下降。

本发明针对现有的液晶显示器中，由于副畴区亮度非最大值，从而造成整体穿透率显著下降的技术问题。本发明可以解决上述问题。
实施例一：

具体的，所述子像素10的边界的底边和顶边均沿横向水平设置，以便于各信号走线，如扫描线的布置和走线。
具体的，所述像素电极20包括三条主电极21以及与所述主电极21对应连接的支电极22，所述主电极21将所述子像素10中的区域限定为6个畴区。
