PROBLEM TO BE SOLVED: To surely realize driving for lighting accurately cells to be lit and not for lighting accurately cells not to be lit, based on display data. SOLUTION: During a reset period after finish of a sustained discharge period, erasing discharges are executed respectively by applying pulse voltages having mutually different waveforms between a first erasing discharge period having, as an object, lighting cells which were lit during the preceding sustained discharge period and a second erasing discharge period having, as an object, not only lighting cells but also non-lighting cells which were not lit during the preceding sustained discharge period. Hereby, a feeble wall charge which was not completely erased during the first erasing discharge period, namely, the feeble wall charge accumulated on the non-lighting cells by being influenced by the lighting cells, can be erased during the second erasing discharge period. Therefore, the non-lighting cells which are not to be lit essentially are prevented from being lit during the next address period and sustained discharge period, to improve a driving voltage margin. |
