The number of wirings between a scanning circuit and a plurality of scanning lines is decreased with a more simple circuit configuration than a conventional one. The scanning lines are grouped into kN× . . . ×k2 groups. First to Nth groups of gate wirings are included, each of the first to Nth groups being composed of kn (1≦̸n≦̸N) gate wirings. A scanning line drive circuit outputs a first selection scanning voltage which selects the scanning lines in each of the groups every horizontal scanning period to the first group of k1 gate wirings, outputs a second selection scanning voltage which selects the scanning lines in one of groups in a second stage where k2 groups constitute one unit every k1 horizontal scanning periods to the second group of k2 gate wirings, and outputs an mth selection scanning voltage which selects the scanning lines in one of groups in an mth stage where k (m−1) groups in a (m−1)th stage constitute one unit every (k (m−1)× . . . ×k1) horizontal scanning periods to an mth group of km gate wirings.
