Abstract

The embodiment of the invention discloses an array substrate. The array substrate comprises a base substrate, a first insulating layer, a plurality of touch control traces, a plurality of touch control electrode blocks, a pixel connecting part and a plurality of pixel electrodes, wherein the first insulating layer is located above the base substrate, at least one first via hole is formed in the first insulating layer, and the at least one first via hole penetrates through the first insulating layer; the touch control traces are located at the bottom part of the at least one first via hole; the touch control electrode blocks are located above the first insulating layer; at least one touch control trace is corresponding to one touch control electrode block, and the touch control electrode block is electrically connected with the at least one corresponding touch control trace; the pixel connecting part is located at the bottom part of the at least one first via hole, and the pixel connecting part is insulated from the touch control traces; the pixel electrodes are located above the first insulating layer, and the pixel electrodes are electrically connected with the pixel connecting part. According to the array substrate disclosed by the invention, the touch control traces and the pixel connecting part share the at least one first via hole; compared with the prior art, the array substrate disclosed by the invention has the advantages that the first via hole number is small, and an aperture size is relatively small, so that a region that liquid crystal molecular orientation is disordered due to the at least one first via hole is reduced, the size of a corresponding black matrix is reduced, and pixel aperture ratio is further increased.
