Abstract
A driving circuit of an electro-optical device that includes scanning lines divided into two or more groups and two or more common electrodes that correspond to the two or more groups of scanning lines. The driving circuit includes a data line driving circuit and a common signal supply circuit. The driving circuit divides one field of one of the pixels into sub-fields and applies the one of the pixels with on or off voltages during the sub-fields to achieve a desired gray-scale level. During one specific sub-field, the data line driving circuit supplies a data signal of an off voltage regardless of the gray-scale level for the pixel. After the specific sub-field ends, the common signal supply circuit switches a voltage applied to a common electrode of that corresponds to the group of scanning lines that includes the selected scanning line.
