Abstract:
1. An organic electroluminescent device consisting of the following, in order: a transparent substrate; a transparent anode layer; a hole transportation layer consisting of an arylamine; an organic structure consisting of at least one light-emissive layer or at least one light-emissive unit having at least one light-emissive layer; a low resistance electron-transporting layer consisting of cesium and an organic compound; an organometallic complex-containing layer including an organometallic complex compound containing at least one metal ion selected from the group consisting of an alkali metal ion, an alkaline earth metal ion and a rare earth metal ion; a reducing reaction generating layer; and a transparent cathode layer wherein the reducing reaction generating layer is a layer produced by depositing aluminum on the organometallic complex-containing layer, thereby causing an oxidation-reduction reaction therebetween; and wherein the cathode consists of ITO.
