Abstract
A pair of substrates forming the active matrix liquid crystal display are fabricated from resinous substrates having transparency and flexibility. A thin-film transistor has a semiconductor film formed on a resinous layer formed on one resinous substrate. The resinous layer is formed to prevent generation of oligomers on the surface of the resinous substrate during formation of the film and to planarize the surface of the resinous substrate.
