<p>An organic electroluminescence device has at least hole-transport layer and a light-emitting layer made of a phosphorescent light-emitting material and a host material between a cathode and an anode. The triplet energy of the hole-transport material of the hole-transport layer is 2.52 to 3.70 eV. The hole mobility at an electric field strength of 0.1 to 0.6 MV/cm is 10<-6> cm<2>/Vs. Thus an organic electroluminescence device using phosphorescence emission, exhibiting a high emission efficiency, and having a long life is provided.</p>
