Abstract

An organic electroluminescence element includes an anode, an organic light emitting layer disposed on an upper side of the anode, a functional layer which is disposed over the organic light emitting layer, in which a rare earth metal and other material are present mixedly, and in which part of the rare earth metal is oxidized, and a cathode disposed on an upper side of the functional layer. A method of manufacturing an organic electroluminescence element includes forming an anode, forming an organic light emitting layer on an upper side of the anode, forming over the organic light emitting layer a functional layer in which a rare earth metal and other material are present mixedly and part of the rare earth metal is oxidized, and forming a cathode on an upper side of the functional layer.
