ABSTRACT:
The present invention relates to a field effect transistor (FET element) in which a .pi.-conjugated polymer film serving as a semiconductor layer is manufactured by first forming a .pi.-conjugated polymer precursor film using a .pi.-conjugated precursor which is soluble in a solvent and then changing the precursor polymer film to the .pi.-conjugated polymer film. A liquid crystal display apparatus uses the FET element as an active drive element. A large number of the FET elements can be manufactured on a large area substrate at the same time at lost cost and operate stably. A large current flow between the source and drain can be significantly modulated by a voltage applied to the gate of the FET element.
