Abstract

See full text

A display panel and a display apparatus are provided. The display panel includes a substrate, a light-emitting component layer and a light-extraction layer. An orthographic projection of a first-color light-emitting component of the light-emitting component layer overlaps with an orthographic projection of a first light-extraction structure of the light-extraction layer. An orthographic projection of the first light-extraction structure overlaps with an orthographic projection of the first-color light-emitting component. First light-extraction structures includes first sidewalls including first sub-sidewall and second sidewalls. A maximum angle α1 formed between a tangent plane of the first sidewall and the plane of the substrate is greater than a maximum angle α2 formed between a tangent plane of the second sub-sidewall and the plane of the substrate.
