The array substrate includes gate lines, common electrode lines, and common electrodes and pixel electrodes arranged on the substrate, and the common electrodes are electrically connected to the common electrode lines through the common electrode via holes; the common electrodes are in the area corresponding to the common electrode via holes It includes a hollowed out part and a reserved part; the reserved part is located between the gate line close to the common electrode line and the pixel electrode close to the common electrode line, and is electrically connected to the common electrode line through the common electrode via hole; wherein, the reserved part is connected to the gate line and the pixel electrode close to the common electrode line. The pixel electrode has no overlap; the hollowed out part is located at least on the side of the reserved part close to the gate line and between the reserved part and the gate line, and / or the hollowed out part is located at least on the side of the reserved part close to the pixel electrode And it is located between the reserved part and the pixel electrode.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a mask plate, an array substrate, a display panel and a display device. Background technique [0002] With the development of liquid crystal display technology, Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is widely used in various fields. [0003] The existing thin film transistor liquid crystal display includes an array substrate, a liquid crystal layer and a cell substrate. As shown in Figure 1(a) and Figure 1(b), the structure of an array substrate is that the common electrode 10 is arranged on the array substrate, and the common electrode via hole is formed by etching the gate insulating layer 601 and the passivation layer 602 50 to electrically connect the common electrode 10 to the common electrode line 30 . [0004] However, in the manufacturing process of the actual array substrate, due to objective reasons such as equipment and technology, ...
