The present application provides a display panel and a display device. The display panel includes a color filter substrate, an array substrate, a liquid crystal layer and a backlight module. Backlight modules are used to provide collimated light. The display panel includes several pixel units. The color filter substrate corresponding to each pixel unit includes a transparent first transmission area and an opaque first non-transmission area, and the array substrate corresponding to each pixel unit includes a transparent second transmission area and an opaque second transmission area. Two non-transmissive regions. The orthographic projection of the first non-transmissive region on the array substrate completely covers the second transmissive region. When the pixel unit works in the opaque mode, the liquid crystal layer corresponding to the pixel unit is used to transmit the collimated light, and the first non-transmission area is used to prevent the collimated light from being emitted from the color filter substrate. In the display panel provided by the present application, the first non-transmissive area completely covers the second transmissive area, so that the pixel unit does not leak light in the opaque mode, which can not only improve the contrast, but also simplify the structure of the display panel.
Description
technical field [0001] The present application relates to the field of display panels, and in particular, to a display panel and a display device. Background technique [0002] At present, LCD (Liquid Crystal Display, liquid crystal display) is a mainstream display widely used in various industries, and LCD has the advantages of thin appearance and light weight. The existing LCD display panel controls the output path of the backlight through two layers of polarizers and a liquid crystal layer in the middle, so that the pixel units have different brightness, and then display colorful pictures through the combination of different light intensities of three colors of red, green and blue. [0003] However, the existing LCD display panel has a large number of optical film layers and a large thickness, and when a black picture is displayed, a certain amount of backlight still leaks out, so that it cannot display pure black, and it is difficult to improve the contrast ratio. In or...
