Abstract:
An organic electroluminescence (EL) element including: an anode; a first functional layer above the anode, the first functional layer having at least one of a hole injection property and a hole transport property; a light-emitting layer above the first functional layer, the light-emitting layer including an organic light-emitting material doped with an electron donor material; a second functional layer above the light-emitting layer, the second functional layer having at least one of an electron injection property and an electron transport property; and a cathode disposed above the second functional layer, wherein carrier density of the light-emitting layer is from 1012/cm3 to 1019/cm3.
