The present invention relates to a plasma display panel device. The plasma display panel device includes a set-up period, a first set-down period, and a second set-down period in this order. During the set-up period, a voltage of a reset signal gradually rises. During the first set-down period, the voltage gradually falls down from a positive voltage. During the second set-down period, the voltage falls down to a negative voltage. The plasma display panel device may reduce the incidence of bright spots because there is no abrupt variation in voltage during a reset period for a reset signal, and this may improve image quality of the plasma display panel device.
