Abstract
Abstract A plasma display device is disclosed having a number of anode pairs disposed on a front panel. Barrier ribs are disposed on the front panel spaced at predetermined intervals. Each anode pair includes odd and even anodes. The odd and even anodes of a given anode pair are partially buried in a corresponding rib.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A plasma display panel comprising: front and rear plates spaced part by a predetermined distance from each other, at least one of said front and rear plates being transparent; a plurality of elongate barrier ribs arranged parallel to each other between the front and rear plates, a plurality of elongate cathodes arranged perpendicular to the barrier ribs on the rear plate, such that a discharge space is formed between said front plate, said cathodes and adjacent barrier ribs, the discharge space being filled with gas; a plurality of elongate anode pairs arranged perpendicular to the cathodes on the front plate in such a manner that every other one of said plurality of elongate barrier ribs is sandwiched between one of said plurality of anode pairs.
Claim 2
Dependent Claim
125 words
A plasma display panel comprising: front and rear plates spaced part by a predetermined distance from each other, at least one of said front and rear plates being transparent; a plurality of elongate barrier ribs arranged parallel to each other between the front and rear plates, a plurality of elongate cathodes arranged perpendicular to the barrier ribs on the rear plate, such that a discharge space is formed between said front plate, said cathodes and adjacent barrier ribs, the discharge space being filled with gas; a plurality of elongate anode pairs arranged perpendicular to the cathodes on the front plate in such a manner that every other one of said plurality of elongate barrier ribs is sandwiched between one of said plurality of anode pairs.
Claim 3
Dependent Claim
46 words
A plasma display panel according to claim 1 wherein each anode pair consists of an odd anode and an even anode, and a portion of the barrier rib is sandwiched between an edge of the even anode and pierces the barrier rib and the front plate.
Claim 4
Dependent Claim
133 words
A plasma display panel comprising: front and rear plates spaced apart by a predetermined distance from each other, said front and rear plates being transparent; a plurality of elongate barrier ribs disposed between the front and rear plates; a plurality of elongate cathodes disposed on the rear plate, such that a discharge space is formed between said front plate, said cathode and adjacent barrier ribs, the discharge space being filled with gas; a plurality of elongate anode pairs arranged such that a barrier rib is sandwiched between each anode pair and an edge of the even and odd anodes of each anode pair pierces the barrier rib such that a portion of the barrier rib is sandwiched between the edge of the even anode that pierces the barrier rib and said front plate.
Claim 5
Dependent Claim
133 words
A plasma display panel comprising: front and rear plates spaced apart by a predetermined distance from each other, said front and rear plates being transparent; a plurality of elongate barrier ribs disposed between the front and rear plates; a plurality of elongate cathodes disposed on the rear plate, such that a discharge space is formed between said front plate, said cathode and adjacent barrier ribs, the discharge space being filled with gas; a plurality of elongate anode pairs arranged such that a barrier rib is sandwiched between each anode pair and an edge of the even and odd anodes of each anode pair pierces the barrier rib such that a portion of the barrier rib is sandwiched between the edge of the even anode that pierces the barrier rib and said front plate.
Claim 6
Dependent Claim
19 words
A plasma display panel according to claim 3 wherein said barrier ribs are evenly spaced by a predetermined distance.
Claim 7
Dependent Claim
19 words
A plasma display panel according to claim 3 wherein every other barrier rib is sandwiched between an anode pair.
Claim 8
Dependent Claim
33 words
A plasma display panel according to claim 5 wherein the edge of the odd anode that pierces the barrier rib is sandwiched between a portion of the barrier rib and the front plate.
