Abstract
A charge-transporting thin film, which enables the achievement of an organic EL element having excellent durability in cases where the charge-transporting thin film is applied to a hole injection layer of the element, is obtained using a charge-transporting varnish that contains a charge-transporting substance, a nonionic fluorine-containing surfactant and an organic solvent, and wherein the nonionic fluorine-containing surfactant has, for example, a perfluoroalkenyl group-containing perfluorohydrocarbon structure represented by one of formulae (1)-(3) and an alkylene oxide structure.
