ABSTRACT:
Provided are an organic electroluminescent device including an aromatic amine derivative formed of a specific structure having a thiophene structure and an organic thin film layer interposed between a cathode and an anode and formed of one layer or a plurality of layers including at least a light emitting layer, in which at least one layer of the organic thin film contains the aromatic amine derivative alone or as a component of a mixture, the organic electroluminescent device in which molecules hardly crystallize, and which decreases a driving voltage, can be produced with improved yields upon the production of the organic electroluminescent device, and has a long lifetime, and an aromatic amine derivative realizing the organic electroluminescent device.
