Abstract
An organic thin film transistor comprises a base material, a gate electrode, a gate insulating layer, an organic semiconductor layer, a source electrode, and a drain electrode, and further comprises charge injection layers which are provided between the source electrode and a base material side layer of the source electrode and between the drain electrode and a base material side layer of the drain electrode and have a thickness that decreases in a direction opposite to a direction in which the source electrode and the drain electrode face each other on a side of the source electrode facing the drain electrode and a side of the drain electrode facing the source electrode, and is manufactured by scanning a metal layer with a laser so as to form the source electrode and the drain electrode, and dropwise-adding a solution which becomes the charge injection layers to a laser-scanned portion.
