Abstract

The invention provides a COA substrate. The COA substrate comprises a substrate body, a metal layer, a thin film transistor, a colored light filter, a transparent electrode and a liner, wherein a plurality of through holes are formed in the colored light filter, and the liner is arranged in the area corresponding to the through holes in the colored light filter. The invention further provides a liquid crystal display panel and a liquid crystal display device. By arranging the liner in the area corresponding to the through holes, appearance of vacuum bubbles in a liquid crystal layer can be well avoided, so that the image display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a COA substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] In the field of liquid crystal display, in order to avoid the problem of inaccurate alignment of the color filter color resistance on the color filter substrate and the pixel units on the array substrate when the array substrate and the color filter substrate are aligned, LCD panel manufacturers have developed the COA substrate ( ColorFilteronArray), that is, the color filter color resist is directly set on the array substrate, which can better solve the problem of inaccurate alignment between the array substrate and the color filter substrate when the box is aligned. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an existing liquid crystal display panel. The liquid crystal display panel includes a COA substrate...
