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.

A composition for forming an organic film contains a polymer having a partial structure shown by the following general formula (1) as a repeating unit, and an organic solvent. Each of AR1 and AR2 represents a benzene ring or naphthalene ring which optionally have a substituent; W
1
represents a particular partial structure having a triple bond, and the polymer optionally contains two or more kinds of W
1
; and W
2
represents a divalent organic group having 6 to 80 carbon atoms and at least one aromatic ring. This invention provides: a polymer curable even under film formation conditions in an inert gas and capable of forming an organic film which has not only excellent heat resistance and properties of filling and planarizing a pattern formed in a substrate, but also favorable film formability onto a substrate with less sublimation product; and a composition for forming an organic film, containing the polymer.
