One field period includes at least one subfield (SF) group made of at least two successive SFs. In the SF group, in the SF subsequent to a SF in which no sustaining discharge is caused, writing discharge is controlled to cause no sustaining discharge. One of all-cell initializing operation and selective initializing operation to be performed in the initializing period in the top SF of the SF group is determined depending on a signal of an image to be displayed. In the top SF of the SF group, the period allocated to the writing discharge in the case of the selective initializing operation is set longer than the period allocated to the writing discharge in the case of the all-cell initializing operation. This structure provides a plasma display panel and a driving method thereof capable of inhibiting increases in black picture level and displaying images at excellent quality. |
