Problems solved by technology

[0005] The object of the present invention is to provide a COA array substrate and a liquid crystal display panel which have a first pixel electrode and a second pixel electrode, and the first pixel electrode and the second pixel electrode are connected together bypassing the color resist layer, so as to solve the existing problems. The COA array substrate needs to form a through hole on the color resist layer, so that the coverage of the pixel electrode is poor, and cracks or even open circuits are easy to occur; and the formed through hole will lead to poor liquid crystal diffusivity in the subsequent liquid crystal dripping process, affecting product yield. technical issues

Abstract

The invention provides a COA array substrate and a liquid crystal display panel. The COA array substrate comprises a substrate, a first metal layer, a first insulation layer, a semiconductor layer, a second metal layer, a first pixel electrode, a colour resistance layer and a second pixel electrode, wherein the first pixel electrode and the second pixel electrode bypass the colour resistance layer and then are connected together. The COA array substrate and the liquid crystal display panel have the advantages that crack or open circuit of the pixel electrodes is avoided, and liquid crystal mobility is improved, so that yield and quality of products are improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a COA array substrate and a liquid crystal display panel. Background technique [0002] With the development of technology, more and more liquid crystal display devices are used. In order to increase the aperture ratio of the liquid crystal display device and reduce the effect of parasitic capacitance, a COA (Color Filter on array) technology is used to arrange the color filter on the array substrate. [0003] The existing COA array substrate generally adopts the formation of via holes on the color resist layer, through which the pixel electrodes and the drains of the thin film transistors are connected together, which makes the coverage of the pixel electrodes poor, prone to cracks or even open circuits; and the formed vias The hole will lead to poor liquid crystal diffusivity in the subsequent liquid crystal dripping process, which will affect the product yield. [0004]...
