ABSTRACT:
An organic electroluminescent device comprising an organic layer at least having a light emission layer provided between an anode and a cathode, wherein the anode has at least one layer comprised of an alloy containing aluminum as a main ingredient, and the alloy contains at least one element whose work function is relatively smaller than that of the main ingredient as a secondary ingredient, the device being relatively inexpensive, having high reliability and capable of reducing disconnection due to hillock or migration.
