Original Abstract Submitted

An electroluminescent device and a display apparatus, for improving the efficiency and prolonging the service life of the electroluminescent device. The electroluminescent device comprises: an anode comprising a reflective material; a cathode arranged opposite to the anode and comprising a transflective material; n light-emitting functional layers laminated between the anode and the cathode, wherein n is an integer greater than 1; and each light-emitting functional layer comprises a light-emitting layer and an electron transport layer located at the side of the light-emitting layer close to the cathode, wherein the thickness of the electron transport layer in the light-emitting functional layer closest to the cathode is greater than that of the electron transport layers in the remaining light-emitting functional layers; and (n−1) charge generation layers located between two adjacent light-emitting functional layers.
