ABSTRACT:
An organic EL device100including a plurality of emitting layers (15) and (17) between a cathode (18) and (19) and an anode (12), each of the emitting layers (15) and (17) made of a host material having a triplet energy gap of 2.52 eV or more and 3.7 eV or less, and a dopant having a light emitting property related to a triplet state, the dopant containing a metal complex with a heavy metal.
