1. An organic electroluminescence device comprising:
a first electrode;
a second electrode facing the first electrode; and
a plurality of organic layers between the first electrode and the second electrode,
wherein at least one of the organic layers comprises an amine compound;
the amine compound comprises a fluorene group; an aryl group having 6 to 60 ring-forming carbon atoms, which is substituted to the fluorene group; a heteroaryl group having 2 to 60 ring-forming carbon atoms, which is substituted to the fluorene group; and at least one aryl amine or heteroaryl amine group which is substituted to the fluorene group;
all substitutable carbons of the aryl group are substituted with deuterium, and
wherein the amine group is connected to at least one of 3-position carbon or 6-position carbon of the fluorene group.
