An organic electroluminescent device ( 1 ) including at least a cathode ( 3 ), an emitting layer ( 4 ), a hole-injecting layer ( 5 ) and an anode ( 6 ) on a substrate ( 2 ) in this order; the hole-injecting layer comprising a metal oxide: and an organic electroluminescent device including at least a cathode, an emitting layer, a metal oxide layer and an anode in this order on a substrate. As examples of the metal oxide, an oxide of a metal of the groups 3 to 13 in the long form periodic table can be given. |
