WIPO Patent Application WO/2023/273383

A1

Provided in the present disclosure are a display panel and a display device. The display panel comprises: a substrate; a plurality of light-emitting devices having different light-emitting areas, the light-emitting devices being located on the substrate; a first refractive index layer, which comprises a plurality of opening regions corresponding to the light-emitting devices, the projections of the opening regions on the substrate at least partially overlapping with the projections of the light-emitting devices on the substrate, the contour shapes of the cross sections of sidewalls of at least a portion of the opening regions in the direction parallel to the substrate surface comprising a plurality of concave-convex curves, and the first refractive index layer being used to reflect on the sidewalls light emitted by the light-emitting devices; and a second refractive index layer, which is located on the side of the first refractive index layer facing away from the substrate, the second refractive index layer being integrally provided and filling the opening regions, and the refractive index of the second refractive index layer being greater than the refractive index of the first refractive index layer.
