Patent ID: 8373696

Claim:
An electro-optical device comprising: scanning lines; data lines; pixels arranged in correspondence with intersections of the scanning lines and the data lines; and first and second power source lines that supply voltage to the pixels, the pixels each having: a current drive-type element having a first electrode and a second electrode; and a drive transistor that controls a current flowing through the current drive-type element, the drive transistor being connected between the first power source line and the first electrode of the current drive-type element, the second power source line being electrically connected between the drive transistor and the first electrode, a reference voltage being applied to the second electrode, the current drive-type element emitting light during a first period within a one frame period by a second voltage being supplied from the first power source line, the second voltage being higher than the reference voltage, a first voltage lower than the reference voltage being supplied from the second power source line during a second period that is after the first period within the one frame period, and the first power source line supplying the first voltage during the second period.
