Abstract

The invention relates to the technical field of display, in particular to an array substrate, a preparation method of the array substrate and a display panel. The resistance of a common electrode is reduced, and meanwhile, the problems that the manufacturing process is complex and the product reject ratio is increased in order to reduce the resistance of the common electrode in related technologies are solved. The array substrate provided by an embodiment of the invention comprises a substrate, and a gate, a source, a drain, the common electrode, a passivation layer and a pixel electrode whichare sequentially arranged on the substrate and located in each sub-pixel of a display area; the array substrate further comprises a common electrode line; the common electrode line has the same layerand material as the source and the drain; the common electrode is in direct contact with the common electrode line; and the pixel electrode is electrically connected with the drain through a via holein the passivation layer.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] The rapid development of liquid crystal display technology has become a new star in the industry and a bright spot in economic development. With the vigorous development of liquid crystal displays, wide viewing angles, high image quality, and faster response speed have become urgent requirements for liquid crystal display devices. Summary of the invention [0003] The main purpose of the present invention is to provide an array substrate, a preparation method thereof, and a display panel, which are used to reduce the resistance of the common electrode, while the manufacturing process is simple, and can improve the alignment layer caused by the large number of vias in the related art. The problem of uneven coating. [0004] To achieve the above objective, the present invention a...
