    摘要： 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.

    摘要： 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, the organic thin-film layer includes at least one emitting layer, and the at least one emitting layer contains: a host material represented by the following formula (1); and at least one phosphorescent material. Ra—Ar1—Ar2—Ar3—Rb   (1) In the formula (1), Ra, Rb, Ar1, Ar2 and Ar3 each represent a substituted or unsubstituted benzene ring or a substituted or unsubstituted condensed aromatic hydrocarbon ring selected from a group consisting of a naphthalene ring, a chrysene ring, a fluoranthene ring, a triphenylene ring, a phenanthrene ring, a benzophenanthrene ring, a dibenzophenanthrene ring, a benzotriphenylene ring, a benzo[b]fluoranthene ring, a benzochrysene ring and a picene ring.When Ar2 represents a substituted or unsubstituted benzene ring, a substituted or unsubstituted 2,7-phenanthrenediyl group or a substituted or unsubstituted triphenylene ring, [Ra—Ar1—] and [Rb—Ar3—] are groups that are structured differently from each other.
