Abstract:
An organic electroluminescence device includes: an anode; a cathode; and an organic layer interposed between the anode and the cathode, in which the organic layer includes an emitting layer and the emitting layer includes a compound represented by a formula (1) below and a compound represented by a formula (2) below. Az1 of the formula (1) below and Az2 of the formula (2) below are each an azine ring. Cz of the formula (1) below and HAr of the formula (2) below are each a nitrogen-containing heterocyclic ring.
