ABSTRACT:
An organic electroluminescence device includes an anode; a cathode; and at least one organic layer, wherein the at least one organic layer includes a first organic layer which is a light-emitting layer being provided between the anode and the cathode and containing at least one light-emitting material, and the at least one organic layer contains at least one compound represented by formula (I):wherein Q1represents an aromatic heterocyclic ring; each of R1, R2, R3and R4independently represents a hydrogen atom or a substituent; and each of R11, R12and R13independently represents an alkyl group, an aryl group, or an aromatic heterocyclic group, provided that at least one of R11, R12and R13represents an aryl group or an aromatic heterocyclic group.
