ORGANIC THIN FILM TRANSISTOR AND METHOD FOR MANUFACTURING SAME

摘要

The purpose of the present invention is to provide an organic thin film transistor having improved mobility. The present invention provides an organic thin film transistor wherein: a channel section (13a) is provided between a source electrode (11) and a drain electrode (12), said channel section being configured from an organic semiconductor layer (13) containing an organic semiconductor material; the channel section contains a planar organic semiconductor crystal having an average surface roughness (Ra) of 2nm or less per 5 square μm; and the film thickness of the planar organic semiconductor crystal is 40 nm or less.
