Patent ID: 7170094

Claim:
A method of driving a light emitting device in which a first period, a second period and a third period appear in one frame period, comprising: in said first, said second and said third periods, gates of a first transistor and a second transistor included in said light emitting device being connected to each other, the gate and a second terminal of said second transistor being connected to each other, the second terminal of said second transistor being connected to a first terminal of a third transistor included in said light emitting device, a second terminal of said third transistor being connected to a pixel electrode of a light emitting element included in said light emitting device; in said first period, connecting a second terminal of said first transistor to the gate of said third transistor to allow a current determined by a voltage of a video signal to flow between a first terminal and the second terminal of said first transistor, and further, impressing a first voltage to the first terminals of said first and said second transistors; in said second period, electrically separating the second terminal of said first transistor from the gate of said third transistor, and further, impressing said first voltage to the first terminals of said first and said second transistors; in said third period, connecting the second terminal of said first transistor to the gate of said third transistor to impress a second voltage to the gates of said first and second transistors to turn ON said second transistor, and further, impressing a third voltage to the first terminals of said first and second transistors; the polarity of said first voltage and said third voltage being inverted with respect to a voltage of an counter electrode of said light emitting element; and the voltage impressed to said light emitting element in said third period having an inverted bias.
