Abstract:
An aromatic amine derivative with a specified structure. An organic electroluminescence device which comprises one or more organic thin film layers having at least one light emitting layer sandwiched between a cathode and an anode, wherein at least one of the organic thin film layers comprises the aromatic amine derivative singly or in combination. The organic EL device employing the aromatic amine derivative has sufficient lifetime, exhibits an enhanced efficiency of light emission, and emits highly pure blue light.
