Abstract
A small-size and large-capacitance capacitor is provided for the peripheral driving circuit of a liquid crystal display device. A capacitor exhibiting crystalline property is provided on a monocrystalline silicon in the peripheral driving circuit of a liquid crystal display device using an insulator film deposition process used to manufacture TFTs (thin-film transistors) of a display pixel portion and the peripheral driving circuit. The capacitor, using monocrystalline silicon as electrodes and an insulator on the monocrsytalline silicon as a dielectric, has a small size and a large capacitance as compared with a capacitor manufactured on amorphous silicon or monocrytalline silicon, and is thus capable of high quality display.
