Abstract

The invention provides a display panel and a display device. The display panel comprises a display substrate, the display substrate comprises a light-emitting area and a transparent area, and the light-emitting area is adjacent to the transparent area; the display substrate further comprises a light-emitting unit, the light-emitting unit comprises an anode, a light-emitting functional layer and a cathode which are sequentially stacked; the orthographic projection of the cathode on the display substrate covers the light-emitting area; the display substrate further comprises an anti-reflection structure, the anti-reflection structure is arranged on the display side of the display substrate, the anti-reflection structure comprises a color resistance layer and a low-refractive-index layer, and the low-refractive-index layer is arranged on the side, away from the display substrate, of the color resistance layer; the refractive index of the low-refractive-index layer is close to that of air; the orthographic projection of the color resistance layer on the display substrate covers the light-emitting area; and the orthographic projection of the low-refractive-index layer on the display substrate covers the light-emitting area and the transparent area. By arranging the anti-reflection structure, the overall reflectivity of the display panel can be reduced, and the viewing effect of the display panel is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] At present, transparent display products are more and more popular. Transparent display products such as transparent OLED display products. [0003] In the actual evaluation, it was found that the measured reflectance of the transparent OLED display is about 20%. The reflectivity is high, which will affect the contrast between the display screen and the environment, making the visual experience of the display screen unclear, thus affecting the user experience of the product. [0004] Conventional products use polarizers attached to the surface of the display to reduce the reflectivity of the screen, but transparent display products need to have transparency, and the use of polarizers will greatly reduce the light transmittance of the product when it is displayed, so how to reduce the transparency T...
