Abstract

The application discloses a display panel and display device, and belongs to the field of a displayer. The display panel comprises a display zone, a first shading layer, a second shading layer; the display zone comprises a middle display zone and an edge display zone; the first shading layer is arranged in the display zone, and provided with multiple light transmission zones aligned in an array form; the second shading layer is arranged in the display zone and located at the upper part of the first shading layer, a second light transmission zone corresponding to the first light transmission zone is arranged on the second shading layer; the area of the first light transmission zone of the edge display zone is less than that of the first light transmission zone of the middle display zone, the area of the first light transmission zone of the edge display zone is less than that of the second light transmission zone of the edge display zone. On the condition of not changing the area of thelight transmission zone of the second shading layer, the problem of sawteeth at four corners of the display screen can be solved; meanwhile, the distance between every two sub-pixels is not increased,thereby avoiding the risk of a bright dark point.

Description

technical field [0001] The present application relates to the field of displays, in particular to a display panel and a display device. Background technique [0002] With the development of display screen technology, more and more display screens adopt a rounded corner design, that is, the four corners of the display screen are arc-shaped. [0003] In a display screen with rounded corners, since the sub-pixels are arranged in rows and columns, the rounded corners of the display screen cannot be completely filled by sub-pixels, but there are jagged gaps, causing the displayed picture to be out of focus on the display screen. There will be jaggies in the corners. In the following, liquid crystal display (LCD) is taken as an example to explain the method of solving the jaggedness in the four corners of the display screen of the LCD with rounded corner design in the related technology: the black matrix is ​​designed in the light-transmitting area at the four corners of the disp...
