Abstract:
1. An AC plane discharge plasma display panel comprising: a front substrate; a rear substrate; a sealing portion for encapsulating said front substrate and said rear substrate at a peripheral edge portion thereof to seal a discharge gas therein; column ribs extending in a column direction and row ribs extending in a row direction, perpendicular to the column ribs, to thereby define pixel cells in a matrix; a plurality of sustain electrodes and a plurality of scan electrodes such that said sustain electrode faces said scan electrode over a discharge gap in the column direction within each said pixel cell, wherein each said sustain electrode has a first display electrode portion and a first bus electrode portion and each said scan electrode has a second display electrode portion and a second bus electrode portion such that said first display electrode portion faces said second display electrode portion over said discharge gap in each said pixel cell, wherein said first bus electrode portions of said sustain electrodes and said second bus electrode portions of said scan electrodes extend in parallel to the row ribs and are spaced from the row ribs in the column direction, wherein said column ribs and said row ribs form lattice-shaped ribs on said rear substrate, wherein a gap for allowing the discharge gas to pass therethrough is provided between a top of the lattice-shaped rib and said front substrate, wherein the AC plane discharge plasma display panel further comprises projecting portions formed on said front substrate at positions corresponding to intersections of the row and column ribs of the lattice-shaped ribs or formed on the intersections of the row and column ribs of the lattice-shaped ribs, and wherein the projecting portions are configured to prevent spurious light emission.
