Abstract
Scan electrodes are provided separately in addition to sustain electrode pairs generating a sustain discharge. An Address-While-Display drive, in which a scan pulse and a sustain pulse are applied at the same timing, is conducted for each subfield. When scan pulses are applied to the scan electrodes, a wall voltage is generated by a wall charge formed on the dielectric layer located on the scan electrodes. This wall voltage is set higher in the negative voltage direction than the wall voltage generated by a wall charge formed on the dielectric layer located on the sustain electrode pairs. As a result, the display luminance level is increased, increase in the scale of power source circuit can be avoided, and a wide drive margin can be obtained.
