A driver circuit for a plasma display panel has first, second, third, and fourth switches. The first switch is connected to the higher potential side of a sustaining pulse power supply and supplies a current to sustaining electrodes. The second switch is connected to the lower potential side of the sustaining pulse power supply and draws a current from the sustaining electrodes. The third switch is connected to the higher potential side of the sustaining pulse power supply and supplies a current to the scanning electrodes. The fourth switch is connected to the lower potential side of the sustaining pulse power supply and draws a current from the scanning electrodes. Diodes are connected to sustaining electrode blocks for preventing pulses to be generated independently in the sustaining electrode blocks from going around to other sustaining electrode blocks, and diodes are also connected to scanning electrode blocks for preventing pulses to be generated independently in the scanning electrode blocks from going around to other scanning electrode blocks.
