Patent ID: 8248330

Claim:
A method of driving a light emitting device, the light emitting device comprising a plurality of pixels and a plurality of power source lines for supplying a current to the plurality of pixels, each of the plurality of pixels comprising a light emitting element and a transistor for controlling the current supplied to the light emitting element, the method comprising the step of: applying a potential to a gate electrode of the transistor to make the transistor on, wherein an absolute value of a gate voltage when the transistor provided at the pixel in correspondence with a same color is made on differs from an absolute value of the gate voltage when the transistor provided at the pixel in correspondence with other color is made on, and wherein a potential of the power source line for supplying the current to the pixel in correspondence with the same color differs from a potential of the power source line in correspondence with the other color, and wherein the transistor is operated in a saturated region.
