Abstract:
The present application provides a light-emitting device and a display apparatus. The light-emitting device comprises: an anode; a light-emitting layer, located at one side of the anode; and a hole assistance layer, located between the anode and the light-emitting layer. At least one of the light-emitting layer and the hole assistance layer comprises a functional material, and the functional material is configured to be capable of crystallizing at a preset temperature and improving a hole injection capability. The functional material in the light-emitting device can improve a hole transport rate and improve the balance degree of charge carriers injected into the light-emitting layer, thereby prolonging the service life of the light-emitting device under a high-temperature condition.
