To provide an organic electroluminescent device showing various luminescent color tones and having high heat resistance, a long lifetime, high emission luminance, and high emission efficiency, in particular, an organic electroluminescent device capable of preventing the attenuation of emission luminance in association with the driving of the device. Provided is an organic electroluminescent device including: an aromatic amine compound having a specific structure; a cathode; an anode; and one or multiple organic thin film layers having at least a light-emitting layer, the one or multiple organic thin film layers being interposed between the cathode and the anode, in which at least one layer of the one or multiple organic thin film layers contains the aromatic amine compound alone or as a component of a mixture.
为了提供一种有机电致发光器件,该器件可显示各种发光色调,并具有高耐热性、长寿命、高发射亮度和高发射效率,特别是一种能够防止发射亮度随器件驱动而衰减的有机电致发光器件。本发明提供了一种有机电致发光器件,包括:具有特定结构的芳香族胺化合物;阴极;阳极;以及至少具有一个发光层的一层或多层有机薄膜层,该一层或多层有机薄膜层位于阴极和阳极之间,其中一层或多层有机薄膜层中至少有一层单独含有芳香族胺化合物或作为混合物的成分。
