Abstract
A plasma display apparatus with small-sized circuits and of a low cost has been disclosed. The apparatus comprises a display panel, having first electrodes and second electrodes adjacently arranged by turns and third electrodes that extend in the direction intersecting the first electrodes and the second electrodes, opposed to each other so as to sandwich a discharge area therebetween, an X drive circuit that drives the first electrodes, a Y drive circuit that drives the second electrodes, an address drive circuit that drives the third electrodes, and a secondary power supply that uses a pulse relating to the drive signal generated in the X drive circuit or the Y drive circuit.
