Patent ID: 7714813

Claim:
A pixel circuit for driving an electro-optic element with a luminance changing according to a flowing current, comprising: a data line through which a data signal in accordance with luminance information is supplied; first, second, third, and fourth nodes; first and second reference potentials; a pixel capacitance element connected between said first node and said second node; a coupling capacitance element connected between said second node and said fourth node; a drive transistor forming a current supply line between said first node and said third node and controlling a current flowing through said current supply line in accordance with a potential of a control terminal of said drive transistor, said control terminal being connected to said second node; a first switch connected to said third node; a second switch connected between said second node and said third node; a third switch connected between said first node and a fixed potential; a fourth switch connected between said data line and said fourth node; and a fifth switch connected between said fourth node and a predetermined potential; said first switch, said third node, said current supply line of the drive transistor, said first node, and said electro-optic element being connected in series between said first reference potential and said second reference potential.
