Claim:
A plasma display apparatus including at least a first electrode and a second electrode and performing display by using a subfield including a reset period, the plasma display apparatus comprising: a first driving circuit for applying a voltage waveform to the first electrode; a second driving circuit for applying a voltage waveform to the second electrode; and a control circuit for controlling the voltage waveform applied to the first and second electrodes by controlling the first and second driving circuits, wherein the first driving circuit includes: a generation circuit for applying, to the first electrode in the reset period, a rising-slope waveform rising over time until a first voltage; a generation circuit for applying, in the reset period, a falling-slope waveform falling over time until a second voltage which is lower than the first voltage; and a first clamp circuit for generating, in the reset period, a dulled falling waveform falling over time until a third voltage which is lower than the first voltage and higher than the second voltage between the rising-slope waveform and the falling-slope waveform in the reset period, wherein a voltage change per unit of time of the falling waveform is larger than a voltage change per unit of time of the falling-slope waveform, wherein the second driving circuit includes: a circuit for applying, to the second electrode in the reset period, a first direct voltage in a period of applying, to the first electrode, the rising-slope waveform; a circuit for applying, to the second electrode in the reset period, a second direct voltage having a voltage value higher than a voltage value of the first direct voltage in a period of applying, to the first electrode , the falling-slope waveform; and a second clamp circuit for generating, to the second electrode in the reset period, a rising rising-slope waveform rising over time from the voltage value of the first direct voltage until the voltage value of the second direct voltage in the period of applying the falling waveform to the first electrode.
