1. An array substrate, comprising:
a first substrate;
a first metal layer, a second metal layer, and a first transparent conductive layer, wherein the first metal layer, the second metal layer, and the first transparent conductive layer are arranged on one side of the first substrate sequentially, wherein the first metal layer is configured to form metal common electrodes and scan lines, the second metal layer is configured to form data lines, the first transparent conductive layer is configured to form a common electrode layer, and the data lines are crossed with the scan lines to define a plurality of pixel regions, wherein each of the plurality of pixel regions comprises a pixel; and
a second transparent conductive layer, configured to form a pixel common electrode of the pixel;
wherein the pixel common electrode comprises a plurality of pixel electrode branches, and each of the plurality of pixel electrode branches extends along an extension direction of a corresponding one of the data lines; each metal common electrode is arranged between two adjacent of the scan lines, the plurality of pixel electrode branches in a corresponding one of the pixel regions are divided into a first pixel electrode branch and a second pixel electrode branch insulated from the first pixel electrode branch by a corresponding one of the metal common electrodes, and the first pixel electrode branch and the second pixel electrode branch, which are located in the same pixel region, are connected to different TFTs (thin film transistors);
in the extension direction of the corresponding one of the data lines, the first pixel electrode branch and the second pixel electrode branch, which are located in different pixel regions and which are adjacent to each other, are connected to the same TFT; and
an end of the first pixel electrode branch, which is close to one of the scan lines closest to the first pixel electrode branch, is connected to a corresponding one of the TFTs; and an end of the second pixel electrode branch, which is close to the one of the scan lines closest to the second pixel electrode branch, is connected to the corresponding one of the TFTs; so that in the same pixel region of the plurality of pixel regions, a transmission direction of an electric signal in the first pixel electrode branch is opposite to that in the second pixel electrode branch.
