Abstract
Abstract 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 the 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A plasma display panel comprising: a front plate disposed on a side of a viewer; a rear plate disposed parallel to said front plate in an opposing relation; and a pair of opposed electrodes and cell barriers as display elements arranged between said front and rear plates, said cell barriers being of a matrix or linear structure and forming a plurality of cells, wherein said cell barriers are formed by successively printing a phosphor-containing material in an overlapping manner by a screen printing method, and said cell barriers are composed only of the phosphor-containing material.
Claim 2
Dependent Claim
95 words
A plasma display panel comprising: a front plate disposed on a side of a viewer; a rear plate disposed parallel to said front plate in an opposing relation; and a pair of opposed electrodes and cell barriers as display elements arranged between said front and rear plates, said cell barriers being of a matrix or linear structure and forming a plurality of cells, wherein said cell barriers are formed by successively printing a phosphor-containing material in an overlapping manner by a screen printing method, and said cell barriers are composed only of the phosphor-containing material.
Claim 3
Dependent Claim
50 words
The plasma display panel according to claim 1, wherein each of said cell barriers is composed of two portions, each portion having a width corresponding to one half a width of each of said cell barriers, and each portion being formed of a phosphor containing material of a different color.
Claim 4
Dependent Claim
27 words
The plasma display panel according to claim 1, wherein a light absorbing layer is formed on each of said cell barriers on the side of the viewer.
Claim 5
Dependent Claim
96 words
A plasma display panel comprising: a front plate disposed on a side of a viewer; a rear plate disposed parallel to said front plate in an opposing relation; and a pair of opposed electrodes and cell barriers as display elements arranged between said front and rear plates, said cell barriers being of a matrix or linear structure and forming a plurality of cells, wherein said cell barriers are formed by inserting a phosphor-containing material in portions around a photoresist pattern and removing the photoresist pattern, and said cell barriers are composed only of the phosphor-containing material.
Claim 6
Dependent Claim
96 words
A plasma display panel comprising: a front plate disposed on a side of a viewer; a rear plate disposed parallel to said front plate in an opposing relation; and a pair of opposed electrodes and cell barriers as display elements arranged between said front and rear plates, said cell barriers being of a matrix or linear structure and forming a plurality of cells, wherein said cell barriers are formed by inserting a phosphor-containing material in portions around a photoresist pattern and removing the photoresist pattern, and said cell barriers are composed only of the phosphor-containing material.
Claim 7
Dependent Claim
50 words
The plasma display panel according to claim 4, wherein each of said cell barriers is composed of two portions, each portion having a width corresponding to one half a width of each of said cell barriers, and each portion being formed of a phosphor containing material of a different color.
Claim 8
Dependent Claim
27 words
The plasma display panel according to claim 4, wherein a light absorbing layer is formed on each of said cell barriers on the side of the viewer.
