Abstract:
1. An electro-optic device which includes pixels disposed in regions corresponding to intersections between a plurality of scanning lines (Rreal) and a plurality of data lines, the pixels being turned on or off in accordance with data signals, each of the data signals being supplied to the plurality of data lines when the plurality of scanning lines (Rreal) are selected, in which one field is divided into a plurality of sub-fields (Nsf) and the plurality of sub-fields (Nsf) are classified into a first group having a period length formed by equally dividing the one field into a plurality of slots, such that a number of slots in the one field is a division number (Ndiv), and a second group having a period length that is at least four times longer than a period length of the first group, and in which gray scales are controlled in the one field by turning on or off the pixels in each of the plurality of sub-fields (Nsf), the electro-optic device comprising: a scanning line driving circuit which, on the assumption that a quantity of the plurality of virtual scanning lines (Rvir) is greater than or equal to a quantity of the plurality of scanning lines (Rreal), performs interlaced scanning on the plurality of virtual scanning lines (Rvir) by the plurality of scanning lines (Rreal) according to a ratio of the period lengths of the plurality of sub-fields (Nsf) arranged in the one field; and a data line driving circuit which supplies the data signals to the pixels located in a region corresponding to selected scanning lines through the plurality of data lines, when two different values obtained as the division number (Ndiv) of the one field are compared to each other, the division number (Ndiv) is selected such that a quantity of a plurality of reference interlaced scanning lines (Ys) is smaller in the interlaced scanning than a selection period obtained by dividing the one field period by the product of the plurality of sub-fields (Nsf) and the plurality of virtual scanning lines (Rvir).
