ABSTRACT:
An organic EL device of the invention includes an inorganic material layer with a resistivity of less than 20 .OMEGA.-cm disposed between an electrode and a light emitting layer. The inorganic material layer contains at least one of indium oxide, tin oxide, and zinc oxide as a primary component, which is the same material as an anode, and at least one of silicon and germanium as an auxiliary component. This improves physical properties at the electrode-organic layer interface and restrains generation of dark spots, establishing an organic EL device featuring a long life, high efficiency and low cost.
