Abstract
The total number of the scan electrodes is divided into a first scan electrode group and a second scan electrode group. The first scan electrode group drive section for driving the first scan electrode group produces a selection potential and a non-selection potential in the scan period, and supplies scan pulses based on the two potentials in the first half of the scan period. The complex switch section supplies the selection potential produced using the first scan electrode group drive section to the second scan electrode group drive section for driving the second scan electrode group in the latter half of the scan period. The second scan electrode group drive section supplies scan pulses based on the input selection potential.
