PROBLEM TO BE SOLVED: To attain higher quality of a display screen by controlling scanning orders of scanning lines of both of upper and lower surfaces to eliminate a luminance difference in the dividing boundary part of the both surfaces. SOLUTION: Scanning orders of scanning lines of both of upper and lower surfaces are allowed to be controlled. Relating to this device, plural first signal lines are divided into S1-Sm, S1'-Sm' in the vertical direction and switching elements M11-Mnm whose one ends are connected to intersections of the first signal lines S1-Sm, S1'-Sm' and second signal lines G1-Gn are provided for every this division. Scanning signals VG1-VGn/2, VGn-VG(n/2)+1 are supplied from gate drivers 3, 3' to the switching elements M11-Mnm according to scanning directions D1, D2'. Then, relating to this device, the driver 3 scans its selection elements in the order of VG1→VGn/2 and the driver 3' scans them in the order of VGn→VG(n/2)+1.
