Abstract:
A plasma display device comprising;a three-electrode surface discharge AC type plasma display panel including an electrode matrix made of a display electrode arrangement and an address electrode arrangement; a driving circuit for driving the plasma display panel; cells of the plasma display panel having a structure in which a discharge gas space and a fluorescent material are disposed between the display electrode and the address electrode, the fluorescent material emitting light by discharge; the driving circuit performing drive operation of changing a potential of at least one display electrode in each of the cells so as to be different between a start time point and an end time point of display discharge for generating display discharge and following reform of wall charge in cells to be lighted after an addressing process for forming wall charge in the cells to be lighted, wherein concerning the drive operation, a cell voltage between the display electrode and the address electrode at the start time point of the display discharge is set to a voltage lower than a microdischarge start voltage that is measured in advance.
