<p>Forced initializing operation is omitted while address operation is performed stably, light emission related to no gradation display is eliminated, and the contrast is largely improved. In an erasing period, erasing discharge is selectively caused only in the discharge cell having undergone address discharge in the immediately preceding address period. It is assumed that first voltage is derived by subtracting voltage applied to a data electrode from low-side voltage of a sustain pulse, second voltage is derived by subtracting voltage applied to the data electrode from high-side voltage of the sustain pulse, and third voltage is derived by subtracting low-side voltage of an address pulse applied to the data electrode from low-side voltage of a scan pulse. The voltage derived by subtracting the third voltage from the first voltage is not lower than a discharge start voltage where the data electrode is used as the positive electrode and the scan electrode is used as the negative electrode. The voltage derived by subtracting the third voltage from the second voltage does not exceed the sum of a discharge start voltage where the data electrode is used as the positive electrode and the scan electrode is used as the negative electrode and a discharge start voltage where the data electrode is used as the negative electrode and the scan electrode is used as the positive electrode.</p> |
