Abstract
Abstract A DC type plasma display panel wherein a plurality of barriers of a predetermined height are formed parallel to each other within the interval of a predetermined space between the front and rear substrate having one anode embedded in the middle of each barrier and cathodes are arranged on the inner surface of the rear substrate crossing the anodes at right angles avoiding the loss of discharged light due to anode abstraction and realizing higher screen luminance.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
66 words
A plasma display panel comprising: a front and rear substrate separated by a predetermined distance; a plurality of barriers arranged parallel to each other in a direction between the front and rear substrate; a plurality of anodes, each of which is placed within said barriers; and a plurality of cathodes arranged on the inner surface of the rear substrate and at right angles to said anodes.
Claim 2
Dependent Claim
66 words
A plasma display panel comprising: a front and rear substrate separated by a predetermined distance; a plurality of barriers arranged parallel to each other in a direction between the front and rear substrate; a plurality of anodes, each of which is placed within said barriers; and a plurality of cathodes arranged on the inner surface of the rear substrate and at right angles to said anodes.
Claim 3
Dependent Claim
36 words
A plasma display panel as claimed in claim 1, wherein each of said anodes is embedded in the middle of said barrier as an independent unit layer, having only one surface exposed to the discharging space.
Claim 4
Dependent Claim
101 words
A plasma display panel comprising: a front substrate having inner and outer surfaces; a rear plate having inner and outer surfaces, the inner surface opposing the inner surface of said front substrate; a plurality of anodes having upper and lower surfaces and first and second edges, each of said anodes disposed within one of said plurality of barriers such that the upper and lower surfaces are covered by said barriers and only one of the first and second edges is exposed; a plurality of cathodes arranged on the inner surface of the rear substrate and at right angles to said anodes.
Claim 5
Dependent Claim
101 words
A plasma display panel comprising: a front substrate having inner and outer surfaces; a rear plate having inner and outer surfaces, the inner surface opposing the inner surface of said front substrate; a plurality of anodes having upper and lower surfaces and first and second edges, each of said anodes disposed within one of said plurality of barriers such that the upper and lower surfaces are covered by said barriers and only one of the first and second edges is exposed; a plurality of cathodes arranged on the inner surface of the rear substrate and at right angles to said anodes.
