Kind Code:
A1
Abstract:
The present application relates to the technical field of display and provides a display panel and a display apparatus. The display panel comprises: a light-emitting substrate comprising a plurality of light-emitting devices arranged in an array; a first light extraction layer located on a light exit side of the light-emitting substrate and comprising a plurality of first light extraction patterns, the orthographic projection of the first light extraction patterns on the light-emitting substrate at least covering partial areas of the light-emitting devices; a color filter layer comprising a plurality of filter patterns, the orthographic projection of the filter patterns on the light-emitting substrate covering the orthographic projection of the light-emitting devices on the light-emitting substrate; and a second light extraction layer comprising a plurality of second light extraction patterns, the orthographic projection of the second light extraction patterns on the light-emitting substrate being located within the orthographic projection of the filter patterns on the light-emitting substrate. The display panel is high in light utilization rate and good in display effect.
