Disclosed is an organic electroluminescence device in which an organic thin film which is composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains a novel aromatic amine derivative, which has an asymmetric structure wherein two different amine units are bonded through a linking group, by itself or as a component of a mixture, molecules of the organic electroluminescence device. This organic electroluminescence device has a long life.

Disclosed is an organic electroluminescence device in which an organic thin film which is composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains a novel aromatic amine derivative, which has an asymmetric structure wherein two different amine units are bonded through a linking group, by itself or as a component of a mixture, molecules are hardly crystallized, thereby improving the production yield of the organic electroluminescence device. This organic electroluminescence device has a long life.
