Abstract

Provided are: a charge-transporting varnish that contains a charge-transporting substance comprising an oligoaniline derivative represented by formula (1), a charge transporting substance that does not contain fluorine atoms, and an organic solvent; and an organic electroluminescent element including a thin film obtained from the varnish. (In the formula: Rrepresents a hydrogen atom or an alkyl group that may be substituted; Rto Reach independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, or an alkyl group, alkenyl group, alkynyl group, aryl group or heteroaryl group that may be substituted; A represents a prescribed fluorine atom-containing substituent; and k represents an integer from 1 to 20.)
