Abstract: This composition for forming a charge-transporting thin film, which contains an organic solvent and a charge-transporting substance precursor that has a 9-t-butoxycarbonyl carbazole structure in the molecule, yields a thin film that exhibits excellent charge transport properties even when firing is performed at a low temperature. As pertains to the charge-transporting substance precursor, the composition can be prepared using a low-polarity solvent that causes less damage to a substrate or a member comprising an organic compound than is the case with a high-polarity amide-based solvent, etc.
