Abstract

The present disclosure relates to a liquid crystal display panel and a display device. The liquid crystal display panel includes a display area; and a non-display area surrounding the display area, wherein the display area includes a plurality of sub-areas, each of the plurality of sub-areas is provided with a plurality of pixel electrodes, all of the pixel electrodes in a sub-area have an identical brightness control parameter; and the brightness control parameter of the pixel electrodes in at least one sub-area is different from the brightness control parameter of the pixel electrodes in another sub-area. By setting different brightness control parameters based on different temperature rise in the sub-areas, the problem of poor Gamma uniformity of the display panel can be solved, and the possibility of occurrence of ghost can be reduced, thereby increasing display quality of the liquid crystal display panel.
