摘要

The present invention addresses the problem of providing the following: an organic thin-film transistor that demonstrates high carrier mobility and low threshold voltage, and that excels in heat resistance; an organic thin-film transistor manufacturing method; an organic semiconductor composition; an organic semiconductor film; and an organic semiconductor film manufacturing method. This organic thin-film transistor includes, on a substrate, the following: a gate electrode; an organic semiconductor layer that contains an organic semiconductor compound; a gate insulation layer disposed between the gate electrode and the organic semiconductor layer; and a source electrode and drain electrode which are disposed in contact with the organic semiconductor layer and which are connected via the organic semiconductor layer. The organic semiconductor layer touches a resin (C) layer formed of the resin (C), or further contains the resin (C). The organic semiconductor compound has a molecular weight of at least 2000, and includes a repeating unit represented by formula (1).
