Abstract:
A method of fabricating a liquid crystal display device including a field effect transistor comprising:forming a gate electrode on an electrically insulating substrate, the gate electrode being located in a transistor region of the substrate;forming an electrically insulating film on the substrate and covering the gate electrode;forming source and drain electrodes on the electrically insulating film on opposite sides of the gate electrode in the transistor region;forming a display electrode on the electrically insulating substrate in a display region of the substrate, adjacent the transistor region, the drain electrode being electrically connected to the display electrode;forming, in the transistor region, a semiconductor film of a .pi.-conjugated polymer having the chemical structure ##STR16## (where R.sub.1 and R.sub.2 are one of hydrogen, an alkyl group, and an alkoxy group, and n is an integer equal to at least 10), on the source and drain electrodes and on the electrically insulating film between the source and drain electrodes in the transistor region;arranging a transparent plate, including a transparent electrode, opposite and spaced from the .pi.-conjugated polymer film and the display electrode with the transparent electrode opposite the display electrode; andinjecting a liquid crystal material between the transparent and display electrodes and between the transparent plate and the .pi.-conjugated polymer film.
