PROBLEM TO BE SOLVED : To realize a low drive voltage by lowering of an energy barrier in electron injection from a negative electrode into an organic compound layer irrespective of work function of a negative electrode material.
SOLUTION : On a base plate, (a) a positive electrode layer, (b) an organic structure containing at least one luminous layer, (c) a low-resistance electron transport layer as a mixture layer of an electron-donating metal dopant and an organic compound, (d) an organic-metal-complex-containing layer made by including an organic metal complex compound containing at least one kind out of alkaline metal ion, alkali earth metal ion, and rare earth metal ion, (e) a reaction production layer, and (f) a negative electrode layer are laminated in turn, of which, at least either the positive electrode layer or the negative electrode layer is transparent, and the reaction production layer is produced by oxidation reduction reaction through filming of heat-reducing metal, which can reduce metal ion in the organic metal complex compound into metal in the vacuum on the organic-metal-complex-containing layer. |
