Abstract
A thin film that has high flatness and high charge transport properties and enables an organic EL element to achieve excellent luminance characteristics if applied thereto can be obtained by using a charge-transporting varnish which contains a charge-transporting substance, an organosilane compound that is composed of a polymer prepared in advance by subjecting an alkoxysilane compound to hydrolysis-condensation and having a weight average molecular weight of 500-10,000, and an organic solvent, said alkoxysilane compound containing at least one compound selected from among alkoxysilane compounds represented by formulae (1-1) and (1-2). SiR(OR)(1-1) SiR2(OR)(1-2) (In the formulae, each Rindependently represents an alkyl group having 1-20 carbon atoms, which is substituted by Z, or the like; each Rindependently represents an alkyl group having 1-20 carbon atoms, which may be substituted by Z; and each of Zand Zrepresents a halogen atom or the like.).
