Abstract
An organic thin film transistor and a method of manufacturing the same are provided. The transistor has a threshold voltage that can be easily controlled without changing the material forming an organic semiconductor film. The organic thin film transistor includes a gate electrode, a gate insulating film, a source electrode, a drain electrode, and an organic semiconductor film. A threshold voltage controlling film is provided between the gate insulating film and the organic semiconductor film.
