Claim 9:
10. An organic electroluminescent device comprising:
a first electrode;
a second electrode; and
an organic material layer having one or more layers disposed between the first electrode and the second electrode,
wherein the organic electroluminescent device further comprises a hole injection or transporting layer or a charge generating layer which is disposed between the first electrode and the organic material layer, between the second electrode and the organic material layer, or when the organic material layers has two or more layers disposed between the first electrode and the second electrode, between the two or more layers, and is composed of a metal oxide comprising one or more transition metals selected from Mo, W, or Re, and one or more metals selected from Cd, or Au,
and
wherein an atomic ratio of the one or more transition metals selected from Mo, W, or Re among the total metal atoms in the hole injection or transporting layer or the charge generating layer is 50 at % to 99.9 at %.
