Abstract:
An organic electroluminescence (EL) element including an anode, a light-emitting layer above the anode, a first functional layer on and in contact with the light-emitting layer, a second functional layer on and in contact with the first functional layer, and a cathode above the second functional layer. A lowest unoccupied molecular orbital (LUMO) level of the first functional layer is lower than at least one of a LUMO level of the second functional layer and a Fermi level of a metal material included in the second functional layer.
