Problems solved by technology

However, the curved screen can only solve the glare problem caused by specular reflection at the center of the curved screen, while specular reflection still occurs at other positions, so that the light reflected by the specular surface will still enter the human eye; in addition, attaching an anti-glare film cannot solve the problem of diffuse glar

Abstract

The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. Compared with the prior art, ambient light entering the human eyes after being reflected by the surface of the display panel can be reduced. The display panel is arranged on an inverted reflection layer on the light emitting layer, the inverted reflection layer comprises an inverted reflection region and a transmission region, and the inverted reflection region is used for reflecting light emitting to the inverted reflection region in the negative direction of the incident direction or the negative direction close to the incident direction, wherein the display panel comprises a pixel region and a pixel definition region for defining the pixel region. In the thickness direction of the display panel, the pixel region and the transmission region have the overlapped region.

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] With the rapid development of display technology, various display devices emerge as the times require. However, the current design of display devices is generally affected by ambient light. Ambient light is incident on the surface of the display device and reflected on the surface of the display device. The light passes through specular reflection, diffuse reflection, and Fresnel reflection. The information light emitted by the display device will enter human eyes, thereby affecting the viewing effect of the viewer. For example, for a large-size display device, Fresnel reflection occurs on the surface of the display device, and the reflectance of ambient light at different incident angles is different, which will cause the edge of the display device to turn white. After the Fresnel reflected light enter...
