Electrooptical device, control method of electrooptical device and electronic device

An electrooptical device comprising:

• a plurality of scanning lines;
• a plurality of data lines;
• pixels that are provided so as to correspond to intersections between the plurality of scanning lines and the plurality of data lines;
• a scanning line drive unit that supplies a scanning signal to the scanning lines;
• a data line drive unit that supplies a first voltage with a magnitude in accordance with a tone to be displayed to the pixels via the data lines in a first period and supplies a second voltage including a low-potential second voltage and a high-potential second voltage to the data lines in a second period before the first period;
• and
• a control unit that controls the data line drive unit such that a first pattern in which the low-potential second voltage and the high-potential second voltage are sequentially output in the second period in one horizontal scanning period and a second pattern in which only the high-potential second voltage is output in the second period in one horizontal scanning period are switched in accordance with a selected scanning line,
• wherein the control unit controls the data line drive unit such that a supply period of the high-potential second voltage in the second pattern is shorter than a supply period of the high-potential second voltage in the first pattern.
