Abstract
An organic electroluminescent device includes at least one light emission layer from an organic compound, the light emission layer being positioned between an anode electrode and a cathode electrode opposed to the anode electrode, in which an organic layer positioned adjacent to the anode electrode is from an organic compound which includes, as an electron-accepting dopant, an electron-accepting compound having a property of oxidizing the organic compound of said organic layer, said electron-accepting compound being doped to said organic layer in vacuum with a simultaneous evaporation method.
