Abstract:
1. An electro-optical device comprising: a scan line; a data line; a common electrode; a pixel electrode facing the common electrode; a control circuit that supplies a high potential having a predetermined value and a low potential lower than the high potential alternately to the common electrode; a scanning line driving circuit that supplies a scanning signal to the scanning line, a potential of the scanning line changes from a non-selection potential to a selection potential in a period during which the potential applied to the common electrode changes from one of the high potential or the low potential to the other of the high potential or the low potential; and a data line driving circuit that performs a precharge operation for precharging the data line after the potential of the scanning line changes from the non-selection potential to the selection potential in the period during which the potential applied to the common electrode changes from one of the high potential or the low potential to the other, and that supplies a data signal defining the grayscale levels to the data line in a period during which the scanning line is selected and during which the potential applied to the common electrode is maintained at the high potential or the low potential.
