Abstract:
1. A plasma display device comprising: a first bus electrode and a second bus electrode which extend in a first direction and are adjacently disposed; a first display electrode which connects to the first bus electrode, extends from the first bus electrode to the second bus electrode, and has one substantially rectangular form in one discharge space; a second display electrode which connects to the second bus electrode, extends from the second bus electrode to the first bus electrode, and has one substantially rectangular form in one discharge space, and causes sustain discharge to the first display electrode; a driving circuit applying a sustain discharge pulse that rises from low voltage to high voltage in two stages in between the first display electrode connected to the first bus electrode and the second display electrode connected to the second bus electrode, wherein an interelectrode distance in an area where the first display electrode faces the second display electrode varies so as to either increase or decrease continuously in one discharge space and the interelectrode distance includes an interelectrode distance to satisfy a Paschen minimum where a discharge start voltage becomes a minimum value, and wherein, when applying the sustain discharge pulse and causing a first sustain discharge by the low voltage of the sustain discharge pulse and a second sustain discharge being stronger than the first sustain discharge by the high voltage of the sustain discharge pulse, the driving circuit sets an application time of the low voltage of the sustain discharge pulse within 0.5 μs, and sets an application time of the high voltage of the sustain discharge pulse longer than the application time of the low voltage of the sustain discharge pulse.
