Disclosed are an aromatic amine derivative and an organic electroluminescent device including the same. A fluorenyl/silafluorenyl group having an ortho-substituted group is introduced into the structure of the aromatic amine derivative. The aromatic amine derivative may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These novel compounds can provide better device performance.
