Abstract
A display driver includes a common electrode charge storage switch provided between a first capacitor element connection node to which one end of a first capacitor element can be connected and a common electrode voltage output node to which a voltage of a common electrode opposite to a pixel electrode of an electro-optical device through an electro-optical material is supplied, a source charge storage switch provided between a second capacitor element connection node to which one end of a second capacitor element can be connected and a source voltage output node to which a voltage of a source line of the electro-optical device is supplied, and a node short circuit switch provided between the common electrode voltage output node and the source voltage output node.
