Abstract:
A plasma display of this invention includes a front panel, and this front panel includes a substrate, a plurality of display electrode pairs formed in stripes on the substrate, a dielectric layer formed to cover the display electrode pair and the substrate, a dielectric-protective layer formed to cover the dielectric layer, and fine particles containing a crystal of a metal oxide, the fine particles being dispersed on a surface of the dielectric-protective layer. The display electrode pair is provided with a strip-shaped scanning electrode and a strip-shaped sustaining electrode each having a laminate structure of a transparent electrode and a bus electrode. In the surface of the dielectric-protective layer, a first region corresponding to a region facing the bus electrode of the scanning electrode is smaller than a second region corresponding to a region except the first region, with regard to a cover rate of the surface covered with the fine particles. This configuration allows effective increase of a charge accumulation amount in the first region, and also allows suppression of increase of a discharge start voltage.
