Abstract

The present application discloses a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel includes a first substrate and a second substrate oppositely arranged, and a liquid crystal layer located between the first substrate and the second substrate; The side of the first substrate close to the liquid crystal layer is provided with a light-shielding layer; the light-shielding layer includes a photothermal material for converting sunlight directed at the light-shielding layer and visible light in the backlight into heat to improve the the temperature of the liquid crystal layer. The light-shielding layer in this application has both light-shielding effect and light conversion effect. Under low temperature or ultra-low temperature environment, it can absorb sunlight and visible light in the backlight source and convert it into heat, which is beneficial to improve the working temperature of the liquid crystal layer and make the Liquid crystal molecules quickly respond to voltage changes, ensuring normal display of the liquid crystal display panel.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular, to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) includes an array substrate and a color filter substrate assembled together, and a liquid crystal layer located between the array substrate and the color filter substrate. The liquid crystal layer includes liquid crystal molecules, and the liquid crystal display generates images by applying an electric field to the liquid crystal layer. In response to an electric field applied to the liquid crystal layer, the liquid crystal molecules in the liquid crystal layer rotate. Therefore, the electric field changes the orientation of the liquid crystal molecules in the liquid crystal layer, and when the orientation of the liquid crystal molecules changes, the light transmittance of the liquid crystal layer is adjust...
