ABSTRACT:
An organic light-emitting device including a substrate, an anode disposed over the substrate, an organic light-emitting structure disposed over the anode, a cathode buffer layer disposed over the organic light-emitting structure and formed of a material selected to permit high energy deposition of a cathode, and a cathode disposed over the cathode buffer layer and being provided with an electron-injecting dopant which diffuses across the buffer layer to provide an interfacial electron-injecting layer at the interface between the organic light-emitting structure and the cathode buffer layer.
