摘要

Disclosed is an organic electroluminescent device having a light-emitting layer between an anode and a cathode. This organic electroluminescent device is characterized in that a layer (L) is arranged between the cathode and the light-emitting layer in contact with the cathode, and the layer (L) contains an organic compound (A) having an aromatic hydrocarbon ring or heterocyclic ring and a carbonyl group, and one or more metals (B) selected from alkaline earth metals and group III metals.
