Abstract:
1. An electro-optical device, comprising: a plurality of scanning lines; a plurality of data lines; a plurality of pixels that are provided so as to correspond to intersections between the plurality of scanning lines and the plurality of data lines, each of the pixels has a pixel electrode, a common electrode that is disposed so as to be opposite to the pixel electrode, and a switching element that allows, when a selection voltage is applied to the scanning line, the data line and the pixel electrode to enter a conductive state; a scanning line driving circuit that supplies a selection voltage for selecting the plurality of scanning lines in a predetermined order; and a data line driving circuit that supplies, when the scanning line is selected, an image signal to the corresponding data line, wherein an entire screen display mode in which an entire screen is used as a display region and a partial display mode in which a part of the entire screen is used as a display region and the other portion is used as a non-display region are selected, in the entire screen display mode, the data line driving circuit alternately supplies a positive polarity image signal and a negative polarity image signal to the data lines on the basis of a predetermined voltage that is greater than a voltage applied to the common electrode, and in the partial display mode, the data line driving circuit alternately supplies a positive polarity image signal and a negative polarity image signal to the data lines on the basis of the voltage applied to the common electrode; wherein the data line driving circuit has a correction circuit that corrects the positive polarity image signal and the negative polarity image signal by a predetermined voltage greater than the voltage applied to the common electrode in the partial display mode.
