A plasma display panel comprises a front plate disposed on the side of a viewer, a rear plate disposed in parallel and opposing the front plate, and cell barriers arranged between the front and rear plates of matrix shape or linear shape. The cell barrier is formed of a material including a phosphor. The cell barriers are formed by printing multiple times a phosphor paste containing glass frit in an overlapped manner by a screen printing method. The cell barrier is formed in another method in which a positive pattern of cell barriers are formed on the front or rear plate by using photo resist, a slurry containing a phosphor fills in portions except for the pattern of the photo resist, and the photo resist is thereafter removed to thereby form cell barriers. In the case of the cell barrier of a color display PDP, the cell barrier may be composed of a material containing phosphor of different colors each with a width corresponding to a one half width of the cell barrier.
A method manufacturing a plasma display panel comprising a front plate, a rear plate disposed in parallel to the front panel in an opposing relation, and cell barriers as display elements arranged between the front and rear plates, the cell barriers being of matrix or linear structure forming a plurality of cells, characterized in that the cell barriers are formed by printing phosphor paste containing glass frit multiple times in an superimposing manner by a screen printing method, drying the phosphor/glass paste after each printing, and sintering the phosphor/glass paste after formation of the cell barriers.
A method of manufacturing a plasma display panel comprising a front plate, a rear plate disposed in parallel to the front panel in an opposing relation, and cell barriers as display elements arranged between the front and rear plate, the cell barriers being of matrix or linear structure forming a plurality of cells, characterized in that a positive pattern of cell barriers is formed by applying a photo reisit on the front or rear plate, curing part of the photo resist, removing uncured photo resist leaving the cured photo resist to form the positive pattern, applying a phosphor-containing slurry to portions of the plate not covered by the pattern of the photo resist, drying the phosphor-containing slurry, and removing the photo resist pattern to thereby form cell barriers.
