1. A display panel, comprising:
a substrate;
a plurality of light emitting devices with different light emitting areas, wherein the light emitting devices are arranged on the substrate;
a first refractive index layer, comprising a plurality of opening regions corresponding to the plurality of light emitting devices; wherein projections of the plurality of opening regions on the substrate at least partially overlap projections of the plurality of light emitting devices on the substrate, a contour shape of a cross sections of a side wall of at least part of the plurality of opening regions in a direction parallel to a surface of the substrate comprises a plurality of concave-convex curves, and the first refractive index layer is configured to reflect light emitted by the plurality of light emitting devices on the side wall; and
a second refractive index layer, arranged on a side, facing away from the substrate, of the first refractive index layer; wherein the second refractive index layer is arranged on a whole surface and fills the plurality of opening regions, and a refractive index of the second refractive index layer is greater than a refractive index of the first refractive index layer.
