Patent ID: 7091966

Claim:
An electro-optical device, comprising: a substrate; a plurality of pixel electrodes arranged in a matrix above the substrate; thin-film transistors provided above the substrate to control switching of the pixel electrodes; scan lines provided above the substrate to supply scan signals to put the thin-film transistors into an ON state or an OFF state to gates of the thin-film transistors; data lines provided above the substrate to supply image signals to the pixel electrodes through sources and drains of the thin-film transistors when the thin-film transistors are put into the ON state; and a scan-signal supply circuit that line-sequentially supplies the scan signals to the scan lines and holds the potential of the scan signals, in the middle of changing the potential of the scan signals from a high potential that puts the thin-film transistors into the ON state to a low potential that puts the thin-film transistors into the OFF state and in the middle of changing the potential of the scan signals from the low potential to the high potential, to an intermediate potential between the high potential and the low potential for a predetermined period; the scan-signal supply circuit supplying the scan signals so that, a period in which, of two scan signals supplied to the adjacent scan lines, one scan signal that precedes is changed from the intermediate potential to the low potential, and a period in which the other scan signal that follows is changed from the low potential to the intermediate potential overlap each other.
