Abstract:
1. A display device comprising: a plurality of first potential lines; a plurality of second potential lines; and a plurality of pixel circuits, wherein one of the pixel circuits includes an electro-optic element; a drive transistor; a capacitive element; a first circuit configured to connect a first terminal of said capacitive element to one of said second potential lines while said electro-optic element is disconnected from said drive transistor, said first circuit being directly connected between said first terminal of said capacitive element and said one of said second potential lines; a second circuit configure to sample a signal voltage from a signal line; and a third circuit configured to connect said drive transistor to said electro-optic element, wherein said drive transistor is configured to control a current flowing to said electro-optic element in accordance with a voltage stored in said capacitive element when said third circuit is set in a conductive state, said first circuit is controlled by a control signal supplied via only one scan line, and wherein said first circuit is configured to supply a predetermined potential from said one of said second potential lines to said first terminal of said capacitive element while said electro-optic element is electrically disconnected from said drive transistor by said third circuit, and said first circuit and said second circuit are configured to be sequentially set in a conductive state while said third circuit is set in a cut-off state.
