Abstract

The present invention relates to to an organic electroluminescent device comprising an hole injection layer and electron injection layer with zero-valent metal, and a method of manufacturing the same. In particular the present invention relates to an organic electroluminescent device comprising an anode layer, at least one electron transport layer, at least one electron injection layer, a cathode layer, and an emission layer, wherein the emission layer is arranged between the anode layer and the cathode layer, wherein the at least a first electron transport layer and the injection layer are arranged between the emission layer and the cathode layer, wherein the electron injection layer is arranged in direct contact to the first transport electron layer, wherein the first electron transport layer is arranged nearer to the anode layer and the electron injection layer is arranged nearer to the cathode layer, wherein at least the first electron transport layer comprises an organic phosphine matrix compound, and a first zero-valent alkali metal; and the electron injection layer comprises a second zero-valent metal of an alkaline earth metal and/or rare earth metal, and an alkali metal halide.
