Abstract

Liquid crystal display panels are provided. In the display panel, a first polarization direction of a first polarizer is perpendicular to a second polarization direction of a second polarizer; each pixel unit includes a pixel electrode including a trunk electrode, the trunk electrode includes a first and a second trunk electrodes disposed along a first direction and a second direction, respectively; an angle between the first direction and the first polarization direction is different from a right angle; the trunk electrode defines an area where the pixel unit is located as four domains, each domain is provided with branch electrodes; the branch electrodes in adjacent domains arranged in a row direction form a first angle and a second angle with the first polarization direction respectively, the first angle ranges from 0 to 30 degrees, and the second angle ranges from 60 degrees to 90 degrees.
