Patent ID: 8288948

Claim:
A plasma display panel comprising: a front substrate and a rear substrate that face each other; a barrier wall, disposed on the rear substrate, comprising base portions arranged on either side of a main discharge space and protruding portions protruding on the base portions, and defining stepped spaces on either side of the main discharge space, wherein the stepped spaces are formed according to stepped surfaces formed by the base portions and the protruding portions; a pair of electrodes disposed on the front substrate, the pair of electrodes comprising a scan electrode and a sustain electrode, the scan electrode comprising a transparent scan electrode and an opaque scan bus electrode disposed on said transparent scan electrode, and the sustain electrode comprising a transparent sustain electrode and an opaque sustain bus electrode disposed on said transparent sustain electrode, such that the scan and sustain bus electrodes are adjacent to each other and centrally disposed within the main discharge space; an address electrode disposed on the rear substrate, the address electrode being elongated to cross an elongation direction of the scan electrode, the address electrode generating, together with the scan electrode, an address discharge; a phosphor layer formed across the main discharge space and the stepped spaces; and a discharge gas filled in the main discharge space and the stepped spaces.
