Abstract:
1. An organic electroluminescent device, comprising: a substrate; an anode comprising an inorganic conducting material above the substrate; a cathode comprising an inorganic conducting material above the substrate; an organic emission functional layer interposed between the anode and the cathode, the organic emission functional layer comprising an organic emissive layer; an organic electrode film comprising (a) a first layer of a polycyclic aromatic hydrocarbon compound having a backbone of 3- to 7-membered rings and (b) a second layer of a benzoimidazole derivative having a substituent in the benzene ring, the organic electrode film being provided such that the first layer is disposed in contact with an outer side of the cathode or the second layer is disposed in contact with an outer side of the anode; and an electrode wire on an outer side of the organic electrode film, the electrode wire being above the organic electrode film, the anode, the cathode and the substrate.
