To provide a novel amine compound which is especially suitable for a hole transport material for organic EL devices, and an organic EL device which employs such an amine compound and is excellent in the driving voltage, luminous efficiency and device lifetime. An amine compound represented by the formula (1):
(wherein X is a sulfur atom or an oxygen atom, each of R 1 to R 10 which are independent of one another, is a hydrogen atom, a deuterium atom or a phenyl group, and each of Ar 1 and Ar 2 which are independent of each other, is a C 6-18 aromatic hydrocarbon group, a dibenzothienyl group or a dibenzofuranyl group, which, each independently, may have a substituent consisting of a methyl group, a methoxy group, a dibenzothienyl group, a dibenzofuranyl group or a 9-carbazolyl group.). |
