An organic electroluminescent device is provided to maintain stable luminescent characteristic for a long time by lowering a driving voltage. An organic electroluminescent device includes an anode(2), a charge generation layer(3), a luminescent layer(4), and a cathode(5). The charge generation layer has an area with electron transporting material at the anode side, has an area with hole transporting material, and material for forming a charge transfer complex by an oxidation-reduction reaction with the hole transporting material to be laminated or mixed. The hole transporting material is in a radical cation state. The area with the electron transporting material contacts with the anode. A layer has electron transporting material formed between the anode and the charge generating layer. The layer has the electron transporting material contacting with the anode.
