Abstract

Provided are a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin layer comprising a single layer or plural layers including a light emitting layer is interposed between a cathode and an anode, wherein at least one layer of the above organic thin layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Thus, the organic electroluminescence device is less liable to be crystallized in molecules, improved in a yield in producing the organic electroluminescence device and extended in a lifetime.
