An organic electroluminescent device includes at least one luminescent layer, constituted from an organic compound, provided between a cathode electrode and an anode electrode opposed to the cathode electrode; and an organic compound layer doped with a metal capable of acting as an electron-donating dopant, the organic compound layer being disposed as a metal doping layer in an interfacial surface with the cathode electrode. An emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the metal doping layer. Alternatively, the organic compound layer can be doped with an electron-accepting compound, disposed as a chemical doping layer in an interfacial surface with the anode electrode on the luminescent layer side; wherein an emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the chemical doping layer.
