  • Patent number: 5652067
    Abstract: In an organic electroluminescent device including a substrate and formed thereon a multilayered structure successively having at least an anode layer, an organic electroluminescent layer and a cathode layer, a sealing layer having at least one compound selected from the group consisting of a metal oxide, a metal fluoride and a metal sulfide is further provided on the electrode layer formed later. A hole injecting and transporting layer is preferably provided between the anode layer and the organic electroluminescent layer. An electron injecting and transporting layer may also be provided between the organic electroluminescent layer and the cathode layer. At least one layer of the hole injecting and transporting layer, organic electroluminescent layer and electron injecting and transporting layer may be formed of a polyphosphazene compound or a polyether compound or a polyphosphate compound having an aromatic tertiary amine group in its main chain.
