PROBLEM TO BE SOLVED: To provide an organic EL element which is excellent in transparency and durability, drives on low voltage, emits light of high luminance, using an electrode layer containing a special inorganic compound. SOLUTION: The organic electro-luminescence device 100 is prepared by piling an anode layer 10, an organic light emitting layer 14 and a cathode layer 16 in order. At least one of the anode layer 10 and the cathode layer 16 contains at least one of inorganic compound among group A-1 and at least one compound among group B-1; where group A-1 includes chalcogenides, oxynitrides, nitrides of Si, Ge, Sn, Pb, Ga, In, Zn, Cd, and Mg, while group B-1 includes chalcogenides, oxynitrides, nitrides of lanthanoids. The anode, and so on, containing these special compound provide an organic EL device which is excellent in transparency and durability and emits light of high luminance even if it is driven at low voltage.
