US 2003/0080683 A1 · Plasma display panel and method for manufacturing the same

Abstract

A PDP having a novel cell structure that is superior in light emission efficiency is provided. A conductive film to be display electrodes X and Y is formed on side portions of a wall so that a main surface that contributes to discharge in the display electrode X is disposed so as to be opposed to a main surface of the neighboring display electrode Y via a gas space. A power supplying portion straddling plural cells in the display electrodes X and Y is provided on the upper surface of the wall. The display electrodes X and Y are covered with a dielectric layer that is thin at the side portion and thick at the top portion of the wall.

Claims6

Dependent claims

A plasma display panel comprising:

a pair of substrates being opposed to each other for constituting an enclosure;
a wall disposed at both ends of a discharge cell in a direction for narrowing a gap between the opposed substrates locally;
a conductive film formed on the surface of the wall so as to straddle over the top portion and the side portions of the wall;
and
a dielectric layer for covering the conductive film, wherein the dielectric layer is thicker at the portion covering the top portion than at the portion covering the side portions, so that discharge is generated most easily between the side portions opposed to each other when a voltage is applied between conductive films of neighboring walls.

A method for manufacturing a plasma display panel that includes a pair of substrates being opposed to each other for constituting an enclosure, a wall disposed at both ends of a discharge cell in a direction for narrowing a gap between the opposed substrates locally, a conductive film formed on the surface of the wall so as to straddle over the top portion and the side portions of the wall and a dielectric layer for covering the conductive film, wherein the dielectric layer is thicker at the portion covering the top portion than at the portion covering the side portions, so that discharge is generated most easily between the side portions opposed to each other when a voltage is applied between conductive films of neighboring walls, the method comprising the steps of:

applying a first glass paste containing filler for restricting flow of the paste only to the top portion of the wall;
drying the first glass paste;
applying a second glass paste having more flowability on baking than the first glass paste to the entire wall, so as to cover the dried first glass paste;
drying the second glass paste;
and
baking the dried first glass paste and the second glass paste as a bulk for forming the dielectric layer.
