Abstract

A thin-film transistor device comprising a pixel section including a plurality of pixel electrodes arranged in rows and columns on a substrate and a plurality of thin-film transistors of reverse stagger type, connected as switching elements to the pixel electrodes, respectively, and a drive section including a plurality of thin-film transistors of coplanar type, each having a gate insulating film, for driving the thin-film transistors of the reverse stagger type. A lower insulating film is located beneath the thin-film transistors of the reverse stagger type. The lower insulating film and the gate insulating films of the thin-film transistors of the coplanar type are formed of a first insulating film provided on the substrate.
