PROBLEM TO BE SOLVED: To provide an organic electroluminescent element that has enhanced luminous efficiency and enhanced emission lifetime.SOLUTION: The amine derivative is represented by formula (1). The compound is incorporated into a luminous layer 150 of an organic EL element 100. (Xto Xare each independently H, D, a halogen atom, a substituted/unsubstituted alkyl group, an aryl group, a heteroaryl group or a condensed ring group formed by bonding with an optional adjacent substituent; Arand Arare each independently a substituted/unsubstituted aryl group or heteroaryl group exclusive of a pyrenyl group; and A is a halogen atom)SELECTED DRAWING: Figure 1 |
