ABSTRACT:
An organic electroluminescence device includes: a cathode; an anode; and a single-layered or multilayered organic thin-film layer provided between the cathode and the anode. In the organic electroluminescence device, at least one layer of the organic thin-film layer includes: an organic-electroluminescence-device material represented by a general formula selected from the following formulae (1), (2) and (3); and at least one phosphorescent material. In the formula: A represents a group selected from a 3-fluoranthenyl group, 5-benzo[c]phenanthrenyl group, 6-benzo[c]phenanthrenyl group and 10-benzo[g]chrysenyl group; Ar represents a fused aromatic ring having 10 to 30 carbon atoms and having triplet energy of 2.10 eV or more; and A or Ar is allowed to be substituted by a phenyl group or a naphthyl group.
