Abstract:
An organic EL element includes an anode and a cathode, and an organic compound layer between the anode and the cathode, the organic compound layer including a light-emitting sublayer, wherein the light-emitting sublayer contains a host, a metal complex acting as a first dopant, and a metal complex acting as a second dopant, the metal complex acting as the first dopant includes an unconjugated ligand and a conjugated ligand, and the first dopant has the lowest excited triplet level originating from the lowest excited triplet level of a unconjugated ligand.
