Abstract:
An organic electroluminescence element includes an anode, an organic light emitting layer disposed on an upper side of the anode, a first functional layer disposed over the organic light emitting layer and including NaF, a second functional layer disposed over the first functional layer and including an organic material containing Yb, and a cathode disposed on an upper side of the second 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 a first functional layer including NaF over the organic light emitting layer, forming a second functional layer including an organic material containing Yb over the first functional layer, and forming a cathode on an upper side of the second functional layer.
