Patent ID: 8144090

Claim:
A driver circuit for driving a plurality of source lines of an electro-optical device, the driver circuit comprising: a first source short-circuit circuit that short-circuits a first source line and a source short-circuit node; a second source short-circuit circuit that short-circuits a second source line and the source short-circuit node, the first source line and the second source line being among the plurality of source lines; a first source output operational amplifier and a second source output operational amplifier that respectively output a grayscale voltage corresponding to grayscale data to the first source line and the second source line; a source charge storage short-circuit circuit that short-circuits a source charge storage node and the source short-circuit node, the source charge storage node being connected with one end of a source capacitor; a voltage setting circuit that supplies a given voltage to the source charge storage node; and a node short-circuit circuit that short-circuits a common electrode voltage output node and the source short-circuit node, a voltage outputted to a common electrode of the electro-optical device provided opposite to a pixel electrode through an electro-optical element being applied to the common electrode voltage output node, the voltage setting circuit including an operational amplifier to which a given precharge voltage is input, an output voltage of the operational amplifier being supplied to the one end of the source capacitor, and a high-potential-side power supply voltage of the first source output operational amplifier and the second source output operation amplifier differing from a high-potential-side power supply voltage of the operational amplifier of the voltage setting circuit.
