Abstract

A display panel and a display device are provided. The display panel includes an array substrate, a pixel defining layer, and a light-emitting functional layer including a first light-emitting part, a second light-emitting part, and a third light-emitting part, wherein the first light-emitting part has a lower quantum efficiency. Pixel defining structures include a first pixel defining structure with a light-enhancing material, and the light-enhancing material is configured to emit light of a same color as light emitted by the first light-emitting part under excitation of light emitted by the first light-emitting part.
