1. A liquid crystal display panel, comprising:
an array substrate comprising a first substrate and a plurality of pixel units arranged in an array on the first substrate;
a color filter substrate disposed opposite to the array substrate;
a liquid crystal layer disposed between the array substrate and the color filter substrate;
a first polarizer disposed on a side of the first substrate away from the pixel unit; and
a second polarizer disposed on a side of the color filter substrate away from the array substrate, wherein a first polarization direction of the first polarizer and a second polarization direction of the second polarizer are perpendicular to each other,
wherein each of the pixel units comprises a pixel electrode, the pixel electrode comprises a trunk electrode, the trunk electrode comprises a first trunk electrode disposed along a first direction and a second trunk electrode disposed along a second direction, the trunk electrode defines an area where the pixel unit is located as four domains, any one of the domains is provided with a branch electrode connected to the trunk electrode, and an angle between the first direction and the first polarization direction is different from a right angle; and
wherein the trunk electrode comprises a middle trunk portion and a side trunk portion located at a side of the middle trunk portion, and the branch electrode comprises a middle branch portion and a side branch portion located on a side of the middle branch portion; the middle trunk portion and the middle branch portion are located in a central area of the pixel electrode, a width of the middle trunk portion is larger than a width of the side trunk portion, and a width of the middle branch portion is larger than a width of the side branch portion.
