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.
