PROBLEM TO BE SOLVED: To provide an electro-optic device which prevents a user from visually recognizing changes in the luminance which are caused by varying proportions of lengths of a positive polarity period and of a negative polarity period constituting a unit period, as flickers.SOLUTION: An electro-optic device 1 is driven in such a way that: a plurality of scanning lines on a display panel 10 is selected in a predetermined sequence in each of a positive polarity period when a voltage in a positive polarity with respect to a predetermined potential is supplied as a data signal and in a negative polarity period when a voltage in a negative polarity is supplied as a data signal; the data signal corresponding to a grayscale is supplied to a pixel corresponding to the selected scanning line in each of the positive polarity period and the negative polarity period; a unit period consisting of the positive polarity period and the negative polarity period is repeated to switch polarities of data signals; and proportions of a length of the positive polarity period and a length of the negative polarity period in the unit period are controlled and a repetition cycle of the unit period is controlled to a frequency equal to or higher than a limit of human visibility to flickers.
