ABSTRACT:
In order to fabricate an organic electroluminescent device with good thermal stability and such high durability that its light emission efficiency is retained over a predetermined level for a long time, an anode is formed on a substrate, one or more organic-inorganic compound layers are formed on the anode, and a cathode is formed on the organic compound layers, sequentially. At least one of the organic compound layers comprises a mixed thin film composed of an organic compound dispersed uniformly in an inorganic compound, or a superlattice structure made of an organic compound and an inorganic compound for preventing the thermal degradation of a fluorescent organic compound constituting an emission layer.
