A method of manufacturing a thin-film transistor device improves performance of a complementary TFT circuit incorporated in a thin- and light-weighted image display device or a flexible electronic device, and reduces power consumption manufacturing cost. Electrodes forming n-type and p-type TFTs and an organic semiconductor are made of the same material in both types of TFT by a solution-process and / or printable process method. A first polarizable thin-film is formed on an interface between a gate insulator and a semiconductor, and a second polarizable thin film provided on an interface between source and drain electrodes and the semiconductor film. A complementary thin-film transistor device is manufactured by selectively exposing either the n-type TFT area or the p-type TFT area to light to remove the polarizing function from the first and second polarizable thin films.
