Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display region and a non-display region around the display region. The display panel comprises an array substrate, an opposed substrate opposite to the array substrate, and a liquid crystal layer between the array substrate and the opposed substrate, wherein the opposed substrate comprises a substrate body and a black matrix located at the position, close to the liquid crystal layer, of the substrate body; a color resistance layer is arranged at the position, in the non-display region, of the opposed substrate, and the display region is not provided with a color resistance layer; the color resistance layer is located at the side, away from the substrate body, in the non-display region. According to the technical scheme, the color resistance layer is arranged at the side, away from the black matrix, in the non-display region, namely at the side close to the liquid crystal layer, the situation that part of free charges generated by the black matrix in the non-display region move to the display region of the array substrate can be prevented, the number of the free charges moving to the positions near the liquid crystal layer is reduced, influences of the free charges on liquid crystal deflection are reduced, and accordingly image display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] LCD (Liquid Crystal Display, Liquid Crystal Display) includes an array substrate and a counter substrate that are arranged oppositely and aligned in a box, and a liquid crystal located between the array substrate and the counter substrate. By controlling the deflection angle of the liquid crystal, grayscale display is realized. [0003] Liquid crystal displays are used more and more in modern life, such as mobile phone display screens, notebook computer display screens, MP3 (Moving Picture Experts Group Audio Layer-3) display screens, TV display screens, etc. People have higher and higher requirements for its performance, such as contrast, viewing angle, color saturation and so on. The wide viewing angle display using black and white display is widely used in vehicle display products because of its high...
