Abstract

A display panel and a display apparatus where a peripheral structure surrounds a light extraction structure and has a smaller refractive index than the light extraction structure. The light extraction structure includes a first portion and a second portion located at a side of the first portion away from a substrate. An area of an orthographic projection of the second portion on the substrate is greater than an area of an orthographic projection of the first portion on the substrate. The first portion includes a first sidewall, and the second portion includes a second sidewall. The first sidewall extends away from a first axis. The first axis is perpendicular to the substrate and passes through a center of the orthographic projection of the light extraction structure on the substrate.
