Zusammenfassung:To provide an organic EL element having good injection properties and transport properties of a carrier. Included are: an InGaZnO layer with a composition rich in In2O3 as a transparent electrode contacting a negative electrode; an InGaZnO layer with a stoichiometric ratio of In:Ga:Zn:O=1:1:1:4 as an electron injecting layer; and an InGaZnO layer with a composition rich in Ga2O3 as an electron transport layer contacting a light emitting layer.
