    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.
