Abstract:
An organic electroluminescence element includes at least one intermediate metal layer and at least two light emitting units between an anode and a cathode. The intermediate metal layer is located between the two light emitting units. Further, the intermediate metal layer is made of a metal with a work function of 3.0 eV or lower, and has a thickness of 0.6 to 5 nm.
