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.
Claims6
An organic electroluminescent device comprising at least one light emission layer made from at least one organic compound, the light emission layer being positioned between an anode electrode and a cathode electrode opposed to the anode electrode, and a hole injection layer positioned adjacent to the anode electrode, said hole injection layer being made from at least one organic compound doped with a dopant, said dopant having a property of oxidizing the at least one organic compond of said hole injection layer through Lewis acid chemistry, by vacuum co-deposition of said dopant and said at least one organic compound of said hole injection layer.
