Abstract
A plasma display is disclosed. In the plasma display, a first transistor for applying a low level voltage of a sustain pulse is connected to a high voltage terminal of a scanning circuit and a second transistor for applying a high level voltage of the sustain pulse is connected to a low voltage terminal of the scanning circuit. The first and the second transistors are alternatively turned on during sustain period, and the sustain pulse is applied to the scan electrode.
