    摘要： An organic electroluminescence device includes a first organic thin-film layer and a second organic thin-film layer between an anode and a cathode opposing the anode in this order from the anode side. The first organic thin-film layer includes a specific aromatic heterocyclic derivative A, and the second organic thin-film layer includes a specific aromatic heterocyclic derivative B. The aromatic heterocyclic derivative A and the aromatic heterocyclic derivative B are different from each other. The organic electroluminescence device is capable of driving at a low voltage and has a long lifetime.

    摘要： Provided are a long-lifetime organic electroluminescence device which can be fabricated in an improved yield owing to suppressed crystallization of molecules, and an aromatic amine derivative that realizes the device, i.e., a novel aromatic amine derivative having a specific structure. Specifically provided are an organic electroluminescence device, including an organic thin film layer formed of one or more layers including at least a light emitting layer, the organic thin film layer being interposed between a cathode and an anode, and an aromatic amine derivative for at least one layer of the organic thin film layer, in particular, a hole transporting layer, the derivative having at least one such structure that a substituent in which two or more specific heterocycles are linked to each other, in particular, a substituent in which two or more specific heterocycles are linked through an aryl group is bonded to an amine through an aryl group.
