Abstract
Embodiment of the present application provide a liquid crystal display panel and a display device. In the liquid crystal display panel provided by the embodiments of the present application, by providing a protection film covering the edge area of the top surface of the color resist block in the test area of the first substrate, the phenomenon that the ions in the color resist block diffuse into the liquid crystal layer caused by the damage or missing of the second passivation layer can be prevented, thus solving the technical problem of blackening of the edge area of the liquid crystal display panel, and improving the display quality of the liquid crystal display panel.
Claims19
A liquid crystal display panel, comprising:
- a first substrate;
- a second substrate disposed opposite to the first substrate;
- and
- a liquid crystal layer disposed between the first substrate and the second substrate;
- wherein the first substrate comprises a first base substrate, a TFT layer, a first passivation layer, a color photoresist layer, and a second passivation layer stacked in sequence;
- wherein the first substrate is defined with a display area and a test area defined at a periphery of the display area, and the color photoresist layer comprises a color filter layer disposed in the display area and a test color resist layer disposed in the test area;
- and
- wherein a second passivation layer and a protection film are sequentially stacked on a side of the test color resist layer away from the first substrate, the test color resist layer comprises a plurality of color resist blocks, and the protection film covers at least edge areas of top surfaces of the plurality of color resist blocks;
- wherein a width of each of the edge areas extending inward from an edge of one of the color resist blocks is 1/10 to ½ of a width of the one of the color resist blocks in a same direction.
