A plasma display device and a driving method thereof are provided to increase the contrast characteristic by making the size of voltage of the reset pulse supplied to a scan electrode group including at least one scan electrode, different from that of the reset pulse provided to the another scan electrode group during a setup period of a reset period in at least one subfield of one frame. A plasma display device includes a plasma display panel(500) having plural scan electrodes(Y1~Yn); a scan driving unit(503) for driving the scan electrodes; and a reset pulse control unit(501) controlling the scan driving unit, dividing the scan electrodes into plural scan electrode groups having at least one scan electrode, and making the size of the reset pulse supplied to at least one scan electrode group different from that of the reset pulse fed to the another scan electrode group, during a reset period in at least one subfield of one frame. |
