Abstract:
1. A light emitting device comprising: an anode; a cathode comprising Ag and Mg; a first electroluminescent layer between the anode and the cathode; a second electroluminescent layer between the first electroluminescent layer and the cathode, wherein the first electroluminescent layer and the second electroluminescent layer are overlapped with each other; a first layer; and a second layer, wherein each of the first electroluminescent layer and the second electroluminescent layer comprises a light emitting layer comprising an organic material, wherein the cathode is capable of transmitting light from the first electroluminescent layer and the second electroluminescent layer, wherein the first layer is between the first electroluminescent layer and the second electroluminescent layer, and the first layer comprises an organic compound and an acceptor, wherein the second layer is between the first electroluminescent layer and the first layer, and the second layer comprises an n-type semiconductor, and wherein the first layer has a conductivity of 10
