A plasma display device and a driving method thereof in which, according to an exemplary embodiment, a grayscale value of a unit light is produced by controlling a time for turning on a switch for applying a sustain discharge voltage. According to the driving method, in a sustain period of at least one first subfield, a voltage of the first electrode is gradually increased from a first voltage to a second voltage, the voltage of the first electrode is reduced from the second voltage, and a third voltage higher than the second voltage is applied to the first electrode for a first period.
