Abstract:
1. 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; a first control line; first and second nodes; first and second reference potentials; a drive transistor to form a current supply line between a first terminal and a second terminal and to control a current flowing through said current supply line in accordance with a potential of a control terminal connected to said second node; a pixel capacitance element connected so as to set a voltage between said first node and said second node; a first switch connected between said data line and a first terminal of said pixel capacitance element and controlled by said first control line; and a first circuit to set a potential of a second terminal of said pixel capacitance element to a fixed potential other than ground while said electro-optic element is not emitting light, the first circuit being controlled by at least a second control line that is connected only to the first circuit in the pixel circuit; 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 second reference potential.
