ABSTRACT:
A circuit for driving an electro-optical device, the electro-optical device having a plurality of scanning lines, a plurality of data lines divided into groups, each group having a predetermined number of data lines, and a plurality of pixels disposed to correspond to intersections of the plurality of scanning lines and the plurality of data lines, includes a scanning line driving circuit that selects each of the plurality of scanning lines for each selection period, the selection period including a plurality of data output periods, a plurality of image signal lines that correspond to the groups, a plurality of switching elements that switch between conductive states and non-conductive states of the data lines belonging to each group and the image signal lines corresponding to each group, a control circuit that sequentially switches the switching elements corresponding to each group to the conductive states for each data output period in the selection period, and a voltage output circuit that applies a voltage according to a gray-scale level of each pixel to each image signal line in each data output period of the selection period, and applies a predetermined voltage to each image signal line in a period after the last data output period of the selection period has lapsed.
