PROBLEM TO BE SOLVED: To reduce a time loss caused by a preliminary discharge period while suppressing increase in background brightness due to the preliminary discharge by applying to scanning electrodes a gradually rising 1st preliminary discharge pulse of a polarity opposite to a scanning pulse, and applying a specific 2nd preliminary discharge pulse to maintaining electrodes. SOLUTION: Write discharge is selectively performed to a display cell by applying a scanning pulse to each scanning electrode of a 1st 2nd,..., m-th scanning lines to be sequentially and selectively scanned for a 1st pulse applying period, and also applying a data pulse Wd to a prescribed data electrode. At the same time, in the scanning line to be scanned next, 1st preliminary discharge pulses Wc1, Wc2,..., Wcm having an opposite polarity to the scanning pulse and rising gradually are applied to the scanning electrodes, and 2nd preliminary pulses Wu1, Wu2,..., Wum having the same polarity as the scanning pulse and a lower rectangular and gradually rising voltage are applied to the maintaining electrodes. |
