Problems solved by technology
However, in the existing display panels made by using 4-mask technology, the common electrode generally forms a storage capacitor with the pixel electrode. Since the area of the common electrode is relatively large, the resistance of the common electrode is also relatively large.
In order to reduce the resistance of the common electrode, the prior art usually has an auxiliary electrode connected in parallel with the common electrode, and the auxiliary electrode is arranged on the same layer as the pixel electrode, which will reduce the aperture ratio of the pixel of the display panel, and at the same time increase the capacity of the storage capacitor Generally small, causing the display panel to be prone to flicker

The invention discloses an array substrate and a display panel. The array substrate comprises a substrate; the first electrode layer is arranged on the substrate, and the first electrode layer comprises a pixel electrode; the first insulating layer is arranged on the first electrode layer; the second electrode layer is arranged on the first insulating layer, and the second electrode layer comprises an auxiliary electrode; the second insulating layer is arranged on the second electrode layer; the third electrode layer is arranged on the second insulating layer, and the third electrode layer comprises a common electrode; wherein the orthographic projection of the pixel electrode on the substrate and the orthographic projection of the common electrode on the substrate are at least partially overlapped, a through hole is formed in the second insulating layer, and the auxiliary electrode is connected with the common electrode through the through hole. According to the invention, the auxiliary electrode is arranged on the second electrode layer which is different from the pixel electrode, so that the aperture ratio of the pixel can be improved; in addition, the capacity of the storage capacitor can be increased, so that the problem that the display panel is easy to flicker is solved.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to an array substrate and a display panel. Background technique [0002] Existing liquid crystal displays generally include a liquid crystal display panel and a backlight module. The liquid crystal display panel is usually composed of a color filter substrate, a thin film transistor array substrate and a liquid crystal layer disposed between the two substrates. The rays of the group are refracted out to produce the picture. [0003] Thin film transistor liquid crystal display panels have a wide range of applications due to their advantages of lightness, environmental protection, and high performance. In recent years, in order to simplify the manufacturing process of thin film transistor liquid crystal display panels and reduce costs, the application of 4-mask technology has become more and more common. However, in the existing display panel manufactured by the 4-ma...
