Disclosed is a carbazole compound having a lower ionization potential than N, N′-dicarbazolyl-3,5-benzene. A compound such as an N, N- (bis-methoxycarbonylethylbenzene) -aminobenzenecarbazole derivative has a low ionization potential and is suitable for the production of an organic electroluminescent device as compared with a case where it does not have this composition. A composition having excellent film properties can be obtained. In addition, a display medium having excellent durability, being driven at a lower voltage, easy to manufacture, and having a long life can be obtained. [Selection figure] None |
