Patent ID: 8610644

Claim:
An electro-optical device comprising: a plurality of unit circuits that are disposed in correspondence with intersections of a plurality of scanning lines and a plurality of data lines; a scanning line driving circuit that sequentially selects a scanning line of the plurality of scanning lines for a drive period; and a data line driving circuit that outputs data electric potentials corresponding to gray scale data to the plurality of data lines for a write period, wherein each of the write period and the drive period occur within a unit period, and each of the plurality of unit circuits has: an electro-optical element that has a gray scale level corresponding to the gray scale data; a capacitor element that has a first electrode connected to a capacitor line and a second electrode connected to a data line; and a first switching element that is disposed between the second electrode and the electro-optical element, the first switching element being in a conductive state at a time when the scanning line is selected by the scanning line driving circuit, the conductive state causing the second electrode and the electro-optical element to be electrically connected; wherein capacitor elements of unit circuits connected to a same data line are directly connected to each other.
