An AC plasma display device includes a pair of spaced apart first and second plates. The first plate bears electrodes each extending in a first direction, and the second plate bears paired first and second electrodes each extending in another direction perpendicular to the first direction. The paired first and second electrodes are divided into several groups. Further, the device includes first connecting lines connected to each other, each of which is associated with the first electrodes in one of the groups. Also provided are second connecting lines connected to each other, each of which is associated with the second electrodes in one of the groups. In addition, the device includes first pulse generators, each of which is associated with one of the first connecting lines and second pulse generators, each of which is associated with one of the second connecting lines.

AC plasma display device

A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.
