A driving method of a plasma display device with reduced black luminance is provided. During at least one TV field without a main reset period, the at least one TV field including a first subfield and a second subfield having a reset waveform in a reset period of the first subfield and the second subfield, respectively, the method includes: applying a first scan low voltage or a first scan high voltage to a scan electrode during an address period of the first subfield; and applying a second scan low voltage or a second scan high voltage to the scan electrode during an address period of the second subfield, wherein the first and the second scan low voltages are maintained at a constant level for a period of time in the first and second subfields, respectively, and the first scan low voltage is different from the second scan low voltage.
