Abstract
Aniline derivatives such as those represented by the formula shown, for example, have good solubility with respect to organic solvents, and are able to provide an organic electroluminescent element having excellent luminance characteristics when a thin film containing said aniline derivatives is used as a charge transporting substance in a hole injection layer. (In the formula, DPA represents a diphenylamino group.)
