Abstract
The present invention relates to a plasma display device and a method of driving the plasma display device. A gradually rising waveform and then a falling waveform are applied to the scan electrodes. A rising waveform has a slope different from that of a rising waveform applied in a first sub-field in at least one of sub-fields posterior to the first sub-field.
