摘要： An electroluminescent device, a manufacturing method thereof, and a display apparatus are provided. The electroluminescent device includes an anode layer, a light emitting layer, a cathode layer, a hole transport layer located between the anode layer and the light emitting layer, and a electron transport layer located between the cathode layer and the light emitting layer. The electroluminescent device further includes: a first interface modification layer between the light emitting layer and one of the hole transport layer and the electron transport layer; wherein an energy level of the first interface modification layer matches an energy level of the light emitting layer and an energy level of the one of the hole transport layer and the electron transport layer.
