The luminance of black level of a display image is reduced to improve the contrast, the address discharge is stably caused, and the image display quality of a plasma display apparatus is improved. For this purpose, a specific-cell initializing subfield having an initializing period in which a forced initializing operation is performed in a specific discharge cell is disposed, a pre-reset period is disposed after a sustain period in the subfield immediately before the specific-cell initializing subfield. In the pre-reset period, first auxiliary discharge is caused in the discharge cell having undergone sustain discharge in the sustain period immediately before the pre-reset period. Then, second auxiliary discharge is caused in the discharge cell where the forced initializing operation is performed in the initializing period of the specific-cell initializing subfield immediately after the pre-reset period. |
