Pixel array substrate

A pixel array substrate includes a plurality of pixel structures. Each pixel structure comprises a data line, a scanning line, an active element and a pixel electrode. The pixel electrode comprises afirst sub-pixel electrode and a second sub-pixel electrode. The first sub-pixel electrode includes a first trunk portion, a second trunk portion, and a plurality of first branch portions. The second sub-pixel electrode includes a third trunk portion, a fourth trunk portion, and a plurality of second branch portions. The plurality of data lines of the plurality of pixel structures are arranged in afirst direction. The first sub-pixel electrode and the second sub-pixel electrode of each pixel structure are arranged in the first direction, and the second trunk part and the fourth trunk part of each pixel structure are separated. 一种像素阵列基板包括多个像素结构。每一像素结构包括数据线、扫描线、主动元件及像素电极。像素电极包括第一子像素电极及第二子像素电极。第一子像素电极包括第一主干部、第二主干部和多个第一分支部。第二子像素电极包括第三主干部、第四主干部和多个第二分支部。多个像素结构的多条数据线在第一方向上排列。每一像素结构的第一子像素电极及第二子像素电极在第一方向上排列，且每一像素结构的第二主干部及第四
