ABSTRACT:
A specified aromatic amine derivative having a chrysene structure. An organic electroluminescence device which comprises at least one organic thin film layer comprising a light emitting layer sandwiched between a pair of electrode consisting of an anode and a cathode, wherein at least one of the organic thin film layer comprises the aromatic amine derivative singly or as its mixture component. Organic electroluminescence devices having a long lifetime and a high efficiency of light emission, and aromatic amine derivatives capable of realizing such organic electroluminescence devices are provided.
