Abstract
An organic electroluminescent device includes an anode electrode layer; a cathode electrode layer opposed to the anode electrode layer; a hole injection layer provided adjacent to the anode electrode layer an organic structure 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.
