Patent ID: 7684092

Claim:
A writing circuit of an electro-optical device having a plurality of scanning lines, a plurality of data lines, and a plurality of pixels disposed to correspond to intersections between the plurality of scanning lines and the plurality of data lines, each pixel including: a pixel capacitor having a pixel electrode and a common electrode opposed to the pixel electrode; and a switching element for electrically connecting the corresponding data line to the pixel electrode when the corresponding scanning line is selected, the writing circuit comprising: an inversion circuit that, during a period of time when one scanning line of the plurality of scanning lines is selected, maintains a voltage between a potential of the data line and a predetermined potential for a predetermined time, inverts the maintained voltage with respect to a reference potential, and applies the inverted voltage to the data line after the lapse of the predetermined time, wherein the inversion circuit comprises: a first transistor with a predetermined resistance between the source and the drain after the lapse of the predetermined time in the period of time when one scanning line of the plurality of scanning lines is selected; a second transistor including a gate supplied with a voltage held by a holding element, and wherein a potential difference between a predetermined high potential and a ground potential is resistance-divided by the first and second transistors and the divided potential difference is used as the inverted voltage.
