Abstract:
1. A method of producing a thin film transistor comprising: a gate electrode formation step that forms a gate electrode on a substrate; a gate insulating layer formation step that forms a gate insulating layer on the substrate in such a manner as to cover the gate electrode formed in the gate electrode formation step; a source/drain electrodes formation step that forms a source electrode and a drain electrode on the gate insulating layer; and a semiconductor layer formation step that applies an aqueous solution for semiconductor layer formation which is an aqueous solution comprising at least a single wall carbon nanotube and a surfactant, which is at least one of sodium deoxycholate and sodium dodecylsulfonate, between the source electrode and the drain electrode formed in the source/drain electrodes formation step by a coating process to form a semiconductor layer comprising the single wall carbon nanotube.
