Abstract
A plasma display device includes plural discharge cells each defined by a pair of first and second discharge-sustaining electrodes and an address electrode intersecting therewith. A driving method thereof includes period for addressing the discharge cells and thereby inducing address-discharge therein, and light-emission period for applying repetitive pulse voltages to at least one of the first and second discharge-sustaining electrodes such that the addressed ones of the discharge cells start and sustain main discharge depending upon the presence of the address-discharge to generate light. Second repetitive pulse voltages are applied to the address electrodes to generate pre-discharge, and rise in portions of the light-emission period during which an absolute value of a voltage difference between the first and second discharge-sustaining electrodes does not exceed 0.9×a maximum of an absolute value of a voltage difference between the first and second discharge-sustaining electrodes during the light-emission period.
