In a plasma display apparatus, the address discharge is stabilized, the contrast is sharpened, and the image display quality is improved. A first up-ramp waveform voltage is applied to the scan electrode, and then a voltage causing no discharge to the scan electrode is applied to the scan electrode, in the sustain period of a weak-discharge sustain operation subfield in a discharge cell that is to be subjected to a forced initializing operation in the initializing period of the subfield immediately after the weak-discharge sustain operation subfield. A second up-ramp waveform voltage is applied to the scan electrode after generation of the first up-ramp waveform voltage, in the sustain period of the weak-discharge sustain-operation subfield in a discharge cell that is to be subjected to a selective initializing operation in the initializing period of the subfield immediately after the weak-discharge sustain-operation subfield. |
