Patent ID: 7136058

Claim:
A display apparatus comprising: signal lines and scanning lines which are vertically and horizontally provided in rows on an insulation substrate; display elements formed in the vicinity of the respective intersections of said signal lines and said scanning lines; a scanning line drive circuit which drives said scanning lines; and a signal line drive circuit which is formed on said insulation substrate and drives said signal lines, said signal line drive circuit having: an amplifier which amplifies an analog video signal; and a signal line selection circuit which selects a signal line to which said analog video signal amplified in said amplifier is supplied, said amplifier having: an odd number of inverters which are cascade-connected; first capacitor elements each of which is connected between stages of said inverters and between an input terminal of said inverter on a first stage and an output terminal of said inverter on a last stage; a first power supply line which supplies a power supply voltage to said inverter on said first stage; and a second power supply line which supplies a power supply voltage to said inverters on stages other than said first stage.
