Method for producing an organic electroluminescent device

摘要

An organic electroluminescent device includes an anode electrode layer (1); a cathode electrode layer opposed to the anode electrode layer; a hole injection layer (3) provided adjacent to the anode electrode layer; an organic structure (2) including at least one light-emissive layer or at least one light-emissive unit having at least one light-emissive layer between the anode electrode layer and the cathode electrode layer. At least one of the anode electrode layer and the cathode electrode layer is transparent. The hole injection layer includes a mixed layer of a metal oxide and an organic compound. The mixed layer is formed upon co-deposition of the metal oxide and the organic compound.
