An organic light-emitting device including a substrate, an anodendisposed over the substrate, an organic light-emitting structure disposed over thenanode, a cathode buffer layer disposed over the organic light-emitting structurenand formed of a material selected to permit high energy deposition of a cathode,nand a cathode disposed over the cathode buffer layer and being provided with annelectron-injecting dopant which diffuses across the buffer layer to provide anninterfacial electron-injecting layer at the interface between the organic light-emittingnstructure and the cathode buffer layer. |
