A plasma display device which generates reset discharge in a reset period prior to an address period in the beginning subfields of a one-field display period, and applies two sustain pulses, which have rising timings different from each other by a predetermined period of time and have partly overlapping application periods, to row electrodes forming each row electrode pair after ending a sustain period in a last subfield of the one-field display period to thereby cause erasure discharge in discharge cells where sustain discharge has been caused in the last subfield.

A plasma display panel and a driving method thereof. In the plasma display panel, Y electrodes are divided into a plurality of groups according to a scanning order and a final reset voltage is established to be different for each group. The plasma display panel includes a panel including a plurality of first electrodes and second electrodes, a plurality of selection circuits that are respectively coupled to the plurality of the first electrodes, and a driving circuit coupled to the second terminals of the selection circuits. The driving circuit includes a transistor which allows the voltage at the first electrodes to be reduced in a ramp style in a reset period.

A plasma display device and a method of driving a plasma display panel (PDP) are provided. The plasma display device includes an upper substrate on which a plurality of first electrodes and a plurality of second electrodes respectively corresponding to the first electrodes are formed; and a lower substrate on which a plurality of third electrodes are formed, wherein the first electrodes are respectively 100 [mu]m or more distant apart from the second electrodes, and during a reset period, a voltage that gradually increases is applied to the first electrodes, and at the same time, a positive bias voltage is applied to the third electrodes. Therefore, it is possible to reduce the power consumption of a PDP by driving a PDP including a scan electrode and an address electrode that are sufficiently distant apart from each other in such a manner that a positive bias voltage can be applied to an address electrode during a reset period. In addition, it is possible to improve the luminance of a PDP and the quality of display of images by preventing a misdischarge such as a spot. Moreover, it is possible to prevent a panel driving circuit from malfunctioning and to improve the reliability of a panel driving circuit by applying a positive bias voltage to a plurality of address electrodes at at least two different times so that noise in driving signals can be reduced.
