An electro-optic device includes pixels provided in correspondence with intersections between a number Rreal of plural scanning lines and plural data lines and turned on or off in accordance with data signals each supplied to the data lines when the scanning lines are selected. In the electro-optic device, one field is divided into a number Nsf of plural sub-fields and the number Nsf of sub-fields are classified into a first group having a period length formed by equally dividing one field into plural Ndiv and a second group having a period length corresponding to plural times of the sub-field of the first group. In the electro-optic device, gray scales are controlled in one field unit by turning on or off the pixels in each of the number Nsf of sub-fields. The electro-optic device includes: a scanning line driving circuit which, on the assumption of a number Rvir (where Rvir≧Rreal) of virtual scanning lines including the number Rreal of scanning lines, performs interlaced scanning on the number Rvir of virtual scanning lines by the number of lines according to a ratio of the period lengths of the sub-fields arranged in one field; and a data line driving circuit which supplies the data signals to the pixels located in selected scanning lines through the data lines. When two different values obtained as division number Ndiv of the one field are compared to each other, the division number Ndiv is selected such that a number Ys of reference interlaced scanning lines is smaller in the interlaced scanning and a selection period obtained by dividing the one field period by the product of the number Nsf of sub-fields and the number Rvir of virtual scanning lines is longer.
