Display panel and display device
By incorporating a light filter and a high-refractive-index light extraction section into the OLED display panel, the problems of poor display quality and high power consumption are solved, achieving higher light purity and light extraction rate while reducing cost and thickness.

Abstract
This application relates to a display panel and a display device. The display panel includes a substrate, an isolation structure, a light-emitting functional part, a light-filtering part, and a first light-extracting part. The isolation structure is disposed on one side of the substrate and defines a first opening. At least a portion of the light-emitting functional part is disposed within the first opening. The light-filtering part is disposed on the side of the light-emitting functional part facing away from the substrate, and at least a portion of the light-filtering part is disposed within the first opening. The first light-extracting part is located on the side of the light-filtering part facing away from the substrate, and the orthographic projection of the first light-extracting part on the substrate at least partially overlaps with the orthographic projection of the light-filtering part on the substrate. The refractive index of the first light-extracting part is greater than the refractive index of the light-filtering part. Thus, the display effect of the display panel can be improved while reducing the thickness of the display panel, thereby reducing the cost and power consumption of the display panel.
