The invention provides a display panel and a display device. The display panel comprises: a substrate comprising a plurality of sub-pixel regions; the plurality of light-emitting devices are positioned on one side of the substrate and are in one-to-one correspondence with the sub-pixel regions; the first pixel definition layer is located on the side, away from the substrate, of the light emitting device and comprises first opening areas in one-to-one correspondence with the sub-pixel areas. The multiple quantum dot layers are located on the side, away from the substrate, of the light-emitting device and located in at least part of the first opening areas; a plurality of first refractive index patterns between the light emitting device and the quantum dot layer; the refractive index of the quantum dot layer is greater than that of the first refractive index pattern. 本公开提供了一种显示面板及显示装置。显示面板包括：衬底基板，包括多个子像素区；多个发光器件，位于衬底基板的一侧，与子像素区一一对应；第一像素定义层，位于发光器件背离衬底基板的一侧，包括与子像素区一一对应的第一开口区；多个量子点层，位于发光器件背离衬底基板的一侧，且位于至少部分第一开口区内；多
