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.
提供了一种有机电致发光器件,包括一个具有噻吩结构的特定结构的芳香胺衍生物和一个有机薄膜层,该有机薄膜层位于阴极和阳极之间,形成为一个或多个层,包括至少一个发光层,其中有机薄膜的至少一层仅含有芳香胺衍生物或作为混合物的组分之一,该有机电致发光器件中分子几乎不结晶,降低了驱动电压,在生产有机电致发光器件时可以提高产量并具有长寿命,以及实现该有机电致发光器件的芳香胺衍生物。
