Abstract
A driver circuit for driving source lines of an electro-optical device includes first and second source short-circuit circuits that respectively short-circuit first and second source lines and a source short-circuit node, a source charge storage short-circuit circuit that short-circuits a source charge storage node connected with one end of a source capacitor and the source short-circuit node, 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 output 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.
