Abstract
An apparatus includes a display panel and a display apparatus. The display panel includes: 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 includes opening regions corresponding to the light-emitting devices, projections of the opening regions on the substrate at least partially overlapping with 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 including concave-convex curves, and the first refractive index layer being used to reflect light emitted by the light-emitting devices on the sidewalls; and a second refractive index layer, which is located on the side of the first refractive index layer facing away from the substrate.
