Patent ID: 7355459

Claim:
An electro-optical device, comprising: a plurality of scanning lines; a plurality of data lines; a plurality of power source lines; a plurality of first pixel circuits; and a plurality of second pixel circuits, the plurality of scanning lines including a plurality of first scanning lines and a plurality of second scanning lines, each of the plurality of first pixel circuits including a first electro-optical element for a first color, a first driving transistor and a first switching transistor having a first drain, a first source and a first gate, each of the plurality of second pixel circuits including a second electro-optical element for a second color that is different from the first color, a second driving transistor and a second switching transistor having a second drain, a second source and a second gate, the first driving transistor being coupled to a first power source line of the plurality of power source lines, the second driving transistor being coupled to a second power source line of the plurality of power source lines, the first gate being coupled to one first scanning line of the plurality of first scanning lines, the second gate being coupled to one second scanning line of the plurality of second scanning lines, one of the first drain and the first source being coupled to one data line of the plurality of data lines, and one of the second drain and the second source being coupled to the one data line.
