Abstract:
An organic electroluminescence element includes an anode, a light-emitting layer disposed over the anode, a functional layer disposed on the light-emitting layer in contact with the light-emitting layer and including a first metal, a light-transmitting conductive layer disposed on the functional layer in contact with the functional layer and composed of a metallic oxide, and a cathode disposed on the light-transmitting conductive layer in contact with the light-transmitting conductive layer and composed of a metal. The functional layer has a film thickness of 15 to 35 nm. A surface of the anode on the light-emitting layer side and an interface between the cathode and the light-transmitting conductive layer are spaced from each other by not less than 150 nm.
