1. A pixel unit, comprising a main pixel area and a sub-pixel area, wherein the main pixel area comprises a main pixel electrode, and the sub-pixel area comprises:
a sub-pixel electrode having at least one domain, wherein the sub-pixel electrode comprises:
a sub-pixel frame electrode disposed at an edge of the sub-pixel electrode;
a first sub-pixel electrode trunk and a second sub-pixel electrode trunk that are perpendicular to each other; and
a plurality of sub-pixel electrode branches extending from the first sub-pixel electrode trunk and the second sub-pixel electrode trunk to the sub-pixel frame electrode; and the sub-pixel electrode branches comprise a first sub-pixel electrode branch, a second sub-pixel electrode branch, a third sub-pixel electrode branch, and a fourth sub-pixel electrode branch,
wherein the first sub-pixel electrode trunk, the second sub-pixel electrode trunk, and the sub-pixel frame electrode divide the sub-pixel area into a first partition, a second partition, a third partition, and a fourth partition; the first partition is provided with the first sub-pixel electrode branch, the second partition is provided with the second sub- pixel electrode branch, the third partition is provided with the third sub-pixel electrode branch, and the fourth partition is provided with the fourth sub-pixel electrode branch, and the fourth partition is located in a lower right area of the sub-pixel area; and an included angle between the fourth sub-pixel electrode branch and a left side of a lower frame electrode of the sub-pixel frame electrode is an obtuse angle;
wherein the fourth sub-pixel electrode branch and the third sub-pixel electrode branch are arranged parallel to each other;
wherein the first sub-pixel electrode branch and the second sub-pixel electrode branch are perpendicular to each other; and the second sub-pixel electrode branch and the third sub-pixel electrode branch are parallel to each other; or
wherein the first sub-pixel electrode branch and the second sub-pixel electrode branch are perpendicular to each other; and the first sub-pixel electrode branch and the third sub-pixel electrode branch are parallel to each other; or
wherein the first sub-pixel electrode branch and the second sub-pixel electrode branch are parallel to each other; and the first sub-pixel electrode branch and the third sub-pixel electrode branch are parallel to each other.
