Patent ID: 11309527

Abstract:
Provided are a display panel and a display apparatus. The display panel includes an organic light-emitting device, which includes an anode, a cathode, a light-emitting layer between the anode and the cathode, and a capping layer located on a side of a light-exiting side electrode facing away from the light-emitting layer and containing an ultraviolet absorber for absorbing ultraviolet light. After absorbing the ultraviolet light, a molecular volume of the ultraviolet absorber is reduced. By adding the ultraviolet absorber, the organic material in the organic light-emitting device is protected from being damaged, and the service life of the organic light-emitting device is prolonged. Since the molecular volume of the ultraviolet absorber is reduced after absorbing ultraviolet light, the refractive index of the capping layer is increased, improving the light extraction efficiency and the light-emitting efficiency of the organic light-emitting device, and also prolonging the service life.
