The present invention is such that a method of driving a plasma display device, the plasma display device including (i) a PDP unit that includes a first and a second substrate arranged so as to face each other, the first substrate having pairs of a first and a second display electrode disposed on a surface that faces the second substrate and a dielectric layer covering the pairs of the first and second display electrodes, and (ii) a PDP driving unit that drives the PDP unit based on an intra-field time division grayscale display method, and includes a plurality of LC resonant circuits for recovering reactive power from power supplied to the display electrodes while driving, the method comprising: a recovering step of recovering the reactive power using the LC resonant circuits during a falling period of a sustain pulse; and a supplying step of supplying the recovered reactive power to the display electrodes during a rising period of the sustain pulse, wherein the PDP driving unit repeats the recovering step and the supplying step cyclically, and in each cycle, the falling period of the sustain pulse applied to the first display electrodes and the rising period of the sustain pulse applied to the second display electrodes overlap at least partially.
