The embodiment of the application provides a display panel and a display device, and belongs to the technical field of display, which comprises a substrate, a driving circuit layer arranged on one side of the substrate, a light-emitting layer arranged on the side, away from the substrate, of the driving circuit layer, wherein the light-emitting layer comprises a pixel definition layer, and the pixel definition layer defines a plurality of pixel openings on the substrate; and an encapsulation structure arranged on the side, away from the substrate, of the light-emitting layer, wherein the encapsulation structure comprises a first encapsulation layer, a second encapsulation layer and a third encapsulation layer arranged in sequence, and the first encapsulation layer is arranged close to the light-emitting layer; wherein the second encapsulation layer is doped with at least one quantum dot material, and the orthographic projection of the second encapsulation layer on the substrate covers the orthographic projection of the pixel definition layer on the substrate. Through the display panel and the display device provided by the embodiment of the application, the color gamut of the display panel can be optimized, and the harmful blue light generated by the display panel can be reduced.
