Claim:
1. An organic electroluminescent device, having a structure in which an anode, an organic layer, and a cathode are laminated on a substrate, wherein at least one layer selected from the group consisting of a light-emitting, layer, a hole-transporting layer, an electron-transporting layer, a hole-blocking layer, an electron-blocking layer, and an exciton-blocking layer contains a carbazole compound represented by the general formula (1): wherein: A represents an n-valent aromatic hydrocarbon group having 6 to 30 carbon atoms, an n-valent aromatic heterocyclic group having 3 to 30 carbon atoms, or an n-valent aromatic group in which two to six of the aromatic hydrocarbon groups and the aromatic heterocyclic groups are linked to each other; n represents an integer of 2 or 3; when the aromatic hydrocarbon group or the aromatic heterocyclic group has substituents, the substituents each independently comprise an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, —OAr, —N(Ar) R's each independently represent hydrogen, an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, —OAr, —N(Ar) Ar's each independently represent an aromatic hydrocarbon group having 6 to 10 carbon atoms, an aromatic heterocyclic group having 3 to 10 carbon atoms, or an aromatic group in which two to three of the aromatic hydrocarbon groups and the aromatic heterocyclic groups are linked to each other; and X's each independently represent oxygen or sulfur.
