An organic electroluminescence device including at least a pair of electrodes and a light-emitting layer sandwiched between them, a derivative having an anthracene substituted as an asymmetric portion as a partial structure, and an amine represented by the formula (1) An organic electroluminescence device comprising a derivative. Embedded image (In the formula, Ar 1 to Ar 4 are each a substituted or unsubstituted aromatic ring having 6 to 50 nuclear carbon atoms, and R 1 and R 2 are the same or different substituents, and are connected to each other to be saturated. Alternatively, an unsaturated ring may be formed, and p is an integer of 1 to 6.) |
