摘要:
A high-density impurity semiconductor region having the same conductivity type as a single-crystal silicon substrate is formed in addition to a main circuit portion of a peripheral circuit on the single-crystal silicon substrate. This semiconductor region is connected to a given potential point directly leading to an electric source. Alternatively, at a part of the peripheral drive circuit, a high-density impurity semiconductor region having a conductivity type reverse to that of the single-crystal silicon substrate is formed, and this semiconductor region is connected to a given potential point directly leading to an electric source. This can solve the problem that photocarriers (electrons and/or holes) caused by the light having not cut off and having entered into the single-crystal silicon region may enter into the peripheral drive circuit through the single-crystal silicon substrate to cause misoperation of the circuit.

The present invention solves problems as follows: a problem that, since light for displaying enters into a semiconductor substrate, carrier induced by light occurs in the semiconductor substrate, potential of the substrate fluctuates, and hence display characteristics become worse; a problem that, in the semiconductor substrate, voltages are applied to the peripheral driving circuits so as to operate the peripheral driving circuits formed in a single-crystal area, which makes display characteristics worse by the voltages being conducted to the display area through the substrate; and a problem that, in case potentials of adjacent pixels greatly differ, the difference locally changes. For this purpose, in a display unit including an active matrix substrate having an image display portion being provided with a plurality of switches and a driving circuit for supplying driving signals to the switches around the image display portion, an opposing substrate opposing the active matrix substrate and having a transparent electrode, and a liquid crystal material between both of the active matrix substrate and the opposing substrate, heavily doped impurity regions having impurity density heavier than that of the semiconductor substrate are formed in the image display portion, and the heavily doped impurity regions are connected to a fixed potential around the image display portion.

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.
