Patent ID: 7274345

Claim:
An electro-optical device, comprising: a plurality of scanning lines; a plurality of data lines; a plurality of pixels arranged correspondingly to intersections of the plurality of scanning lines and the plurality of data lines; and a plurality of first power wiring lines, each of the plurality of pixels further comprising: a first switching transistor an electrical conduction of which is controlled based on a scan signal supplied through a corresponding scanning line of the plurality of scanning lines; an electro-optical element having a pixel electrode, a common electrode, and an electro-optical material therebetween; a driving transistor coupled to the electro-optical element; and a capacitor which has a first electrode and a second electrode forming a capacitance and which is coupled to a gate of the driving transistor through the first electrode, the capacitor holding, as electric charge, a data signal supplied through the first switching transistor and a corresponding data line of the plurality of data lines, an electrical conduction state of the driving transistor being set in accordance with a quantity of electric charge held in the capacitor, and the electro-optical element and the corresponding first power wiring line of the plurality of first power wiring lines being electrically coupled to each other through the driving transistor in accordance with an electrical conduction state thereof, and the second electrode being coupled between the driving transistor and the pixel electrode.
