Abstract:
Provided is a charge-transporting varnish which includes a charge-transporting material including fluorine atoms, a charge-transporting material not including fluorine atoms, a dopant material comprising heteropoly acid, and an organic solvent, said charge-transporting material including fluorine atoms being a polymer of weight-average 1,000 to 200,000 molecular weight obtained by condensing a triarylamine compound, an aryl aldehyde compound including fluorine atoms, and a fluorine derivative having a carbonyl group, and said charge-transporting material not including fluorine atoms being an oligoaniline compound. The charge-transporting varnish provides a thin film which, even in a case of being used as a single layer in contact with and in between an anode and a luminescent layer, is capable of achieving an organic EL element having superior luminance characteristics and durability.
