Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a plurality of sub-pixels and a color film layer, each sub-pixel comprises an opening area and anon-opening area. The color film layer comprises a plurality of color resistance blocks; the sub-pixels comprise first sub-pixels; the color resistance blocks comprise a first color resistance block;the first color resistance block corresponds to the first sub-pixel; the first color resistance block comprises a first light-transmitting part and a second light-transmitting part; the projection ofthe first light-transmitting part on the plane where the substrate is located is at least partially overlapped with the projection of the opening area of the first sub-pixel on the substrate; the projection of the second light-transmitting part on the plane where the substrate is located is at least partially overlapped with the projection of the non-opening area of the first sub-pixel on the substrate, and the transmittance of the first light-transmitting part to the light of the first color is larger than that of the second light-transmitting part to the light of the first color. According to the display panel and the display device provided by the invention, the reflection of external ambient light is reduced, and the light extraction rate of the display panel is increased.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] At present, in order to reduce the reflection of external light in the organic electroluminescent display panel, a polarizer is generally installed on the light emitting surface of the OLED device. The light transmittance of the polarizer is generally about 45%, and the reflectance at a viewing angle of 60° is about 15.5%. Although the polarizer can reduce the reflection of external ambient light, it also greatly reduces the light extraction rate of the OLED device. Contents of the invention [0003] The present invention provides a display panel and a display device to increase the light extraction rate of the display panel while reducing the reflection of external ambient light. [0004] In a first aspect, an embodiment of the present invention provides a display panel, including...
