<p>The present invention provides an aromatic amine derivative having a specific structure including a substituted diphenylamino group attached to a naphthalene structure. This aromatic amine derivative can realize an organic electroluminescent element having high emission luminance and luminous efficiency and having a prolonged lifetime. The organic electroluminescent element includes an organic thin film layer provided between a cathode and an anode. The organic thin film layer has a single layer or multilayer structure including at least a light emitting layer. At least one layer in the organic thin film layer contains the aromatic amine derivative either solely or as a component of a mixture.</p> |
