Abstract:
An organic electroluminescence device includes an anode, a cathode, and an organic thin-film layer interposed between the anode and the cathode. The organic thin-film layer includes a phosphorescent-emitting layer containing a host and a phosphorescent dopant, and an electron transporting layer that is provided closer to the cathode than the phosphorescent-emitting layer. The host contains a substituted or unsubstituted polycyclic fused aromatic skeleton.
