Abstract:
An aromatic amine derivative having a specific structure, an organic electroluminescence device, and an electronic equipment are provided. The organic electroluminescence device includes organic thin film layers which include a light emitting layer and are disposed between a cathode and an anode. At least one layer of the organic thin film layers includes the aromatic amine derivative. The organic electroluminescence device can be operated at low driving voltage and has high efficiency. The compound achieves the above organic electroluminescence device.
