Abstract
The present disclosure provides a display panel and a display apparatus. The display panel includes: light-emitting elements which include a first light-emitting element that emits light of a first color having a wavelength ranging from λ1 to λ2, a second light-emitting element that emits light of a second color having a wavelength ranging from λ3 to λ4, and a third light-emitting element that emits light of a third color having a wavelength ranging from λ5 to λ6; and first to third capping layers respectively covering light-exiting sides of the first to third light-emitting elements. At least one of the first to third capping layers contains an ultraviolet light absorber that can absorb light having a wavelength ranging from 380 nm to 410 nm with an absorption rate greater than or equal to 20%.
