ABSTRACT:
A driving circuit of an electro-optical device wherein one field is divided into p (p is an integer that is equal to or more than two) groups and each group is divided into two sub-fields. The p groups each are set to have the length of a time period that is equal to one another. The 2p sub-fields that constitute the one field are set to different lengths of time periods in such a manner that a boundary between two sub-fields of each group is shifted by a predetermined interval compared to the boundary between the two sub-fields of the preceding group. The different gray scale values are expressed by turning on a single sub-field or n (n is an integral number that is equal to two or more and that is equal to or less than 2p) sub-fields that are adjacent to each other.
