(57) [Problem] To provide an organic electroluminescent device capable of emitting high-luminance light and having heat resistance and long life, and an amine compound contained in an organic compound layer of the device. SOLUTION: An organic compound layer such as a light emitting layer, a hole transport layer and a hole injection layer contains a compound represented by the general formula (I): [Wherein, Ar 1 is an aryl group having 6 to 18 nuclear carbon atoms, Ar 2 to Ar 5 are an arylene group having 6 to 18 nuclear carbon atoms, X 1 is a single bond, —O—, —S—, — (CH 2 ) n — (n is 1 to 6 Or a linking group that is -C (CH 3 ) 2- , which may or may not be present, X 2 and X 3, each single bond, -O -, - S -, - (CH 2) n - (n is an integer from 1 to 6) or -C (CH 3) 2 - indicates a bond group, which may be the same or different. ] And an amine compound represented by the above general formula (I). |
