Abstract: A display panel comprises: a base substrate; a display function layer, comprising multiple light-emitting elements; a light-exit angle limiting layer, comprising a first light-blocking region and multiple first light-exit regions corresponding to multiple light-emitting elements on a one-to-one basis, an orthographic projection of each first light-exit region on the base substrate overlapping with an orthographic projection of a corresponding light-emitting element on the base substrate; a dimming function layer, comprising multiple dimming structures corresponding to multiple light-emitting elements on a one-to-one basis, an orthographic projection of each dimming structure on the base substrate not overlapping with an orthographic projection of a corresponding light-emitting element on the base substrate, the dimming structure being configured to change a direction of propagation of part of the light that is emitted by the corresponding light-emitting element and directed toward the first light-blocking region into a direction toward the corresponding first light-exit region.
