In a plasma display device comprising: plural first, second, and third electrodes disposed adjacently and extending in a first direction, the third electrodes being provided between the first and second electrodes for repeating discharges; a dielectric layer covering the electrodes, a first electrode driving circuit for driving the first electrodes; a second electrode driving circuit for driving the second electrodes; and a third electrode driving circuit for driving the third electrodes, grayscale display is performed by a sub-field method, and the third electrodes are set to have a potential approximately the same as that of the first or second electrode at the discharge in the repetitive discharges. The third electrode driving circuit changes the ratio of the discharges in which the third electrodes operate as cathodes to the discharges in which they operate as anodes in the period when the discharges are repeated, at least in one sub-field. |
