PROBLEM TO BE SOLVED: To provide a plasma display apparatus in which reliable erase discharge is performed and an erroneous discharge is suppressed, even when a discharge sustain period is shortened in correspondence to higher definition. SOLUTION: In the discharge sustain period, a width PWc of a pulse Pc applied in the later part of the discharge sustain period is made larger than the width PWb of a pulse Pb applied in the earlier part of the discharge sustain period, except for an initial pulse Pa in the discharge sustain period. In addition, a called narrow pulse is applied in an erase period to perform an erase discharge. According to this method, wall voltages in discharge cells at the end of the discharge sustain period are raised to a higher level than in the related art. As a result, the reliable erase discharge is performed, and the erroneous discharge is suppressed. COPYRIGHT: (C)2007,JPO&INPIT
