    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 includes at least one phosphorescent material and a host material represented by the following Formula (1). Ra—Ar1—Ar2—Rb  (1) In Formula (1): Ra and Rb each represent a substituted or non-substituted benzene ring or a substituted or non-substituted 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 benzochrysene ring and a picene ring; andAr1 and Ar2 each represent a substituted or non-substituted benzene ring or a substituted or non-substituted condensed aromatic hydrocarbon ring selected from a group consisting of a naphthalene ring, a chrysene ring, a fluoranthene ring, a triphenylene ring, a benzophenanthrene ring, a dibenzophenanthrene ring, a benzotriphenylene ring, a benzochrysene ring and a picene ring.

    摘要： An organic electroluminescence device includes: an anode; a cathode; and an organic thin-film layer provided between the anode and the cathode and including at least three emitting layers. The organic thin-film layer includes: a first emitting layer adjacent to the anode; a second emitting layer adjacent to the cathode; and a third emitting layer interposed between the first emitting layer and the second emitting layer. The first emitting layer, the second emitting layer and the third emitting layer contain phosphorescent dopants. The first emitting layer and the second emitting layer use fused polycyclic aromatic derivatives as host materials.
