ABSTRACT:
An organic electroluminescence element comprising: an anode layer, a cathode layer, and an organic luminescence layer therebetween, the organic luminescence layer having a carbazole derivative with a glass-transition temperature of 110° C. or higher, and a phosphorescent dopant. This structure makes it possible to provide an organic electroluminescence element which can make use of the triplet exciton state of the carbazole derivative even at room temperature and which has a practical life and superior heat-resistance.
