Display panel and display apparatus

A display apparatus comprising a display panel,

• wherein the display panel comprises:
• a substrate;
• a light-emitting component layer provided at a side of the substrate facing towards a light-emitting surface of the display panel and comprising light-emitting components;
• and
• a light-extraction layer disposed at a side of the light-emitting component layer facing towards the light-emitting surface of the display panel and comprising light-extraction structures and a peripheral structure, the peripheral structure surrounding the light-extraction structures and having a refractive index smaller than a refractive index of each of the light-extraction structures,
• wherein the light-emitting components comprise first-color light-emitting components, and an orthographic projection of one of the first-color light-emitting components on the substrate overlaps with an orthographic projection of one of the light-extraction structures on the substrate;
• wherein the light-extraction structures comprise first light-extraction structures, and an orthographic projection of one of the first light-extraction structures on the substrate overlaps with an orthographic projection of one of the first-color light-emitting components on the substrate;
• and
• wherein the first light-extraction structures comprise first sidewalls, wherein the first sidewalls comprise first sub-sidewalls and second sub-sidewalls, a maximum angle formed between a tangent plane of one of the first sub-sidewalls and a plane of the substrate is a first angle α1, and a maximum angle formed between a tangent plane of one of the second sub-sidewalls and the plane of the substrate is a second angle α2, where α1>α2.
