- 4. A plasma-addressed display device as claimed in claim 3, wherein, the discharge electrodes and barrier ribs comprise a conductive pattern and an insulating pattern, respectively, which are obtained by printing one of the patterns superposed on the other using the same screen mask.
- 5. A plasma-addressed display device as claimed in claim 1, wherein, each of the barrier ribs is a printed barrier rib.
- 6. A plasma-addressed display device as claimed in claim 1, wherein, the apices of the barrier ribs are placed in contact with the dielectric sheet.
- 7. A plasma-addressed display device, comprising:
- a first substrate having a plurality of data electrodes arranged in parallel to each other;
- a dielectric sheet, the first substrate and the dielectric sheet being disposed face-to-face to form a display chamber therebetween;
- a second substrate having a plurality of discharge electrodes, and
- a plurality of barrier ribs each of which is located on one of the discharge electrodes to define a discharge channel between adjacent barrier ribs, said barrier ribs covering a portion of said discharge electrodes to prevent electrical discharge at covered portions of said discharge electrodes, the second substrate and the dielectric sheet being disposed face-to face to form a discharge chamber therebetween, the data electrodes and discharge channel being arranged so that they are spaced apart in the vertical and horizontal directions, respectively, each of the discharge electrodes having a width larger than the respective one barrier rib to provide exposed portions of the discharge electrodes at each side of the barrier rib so that the pair of the discharge electrodes belonging to each of the discharge channels is exposed on the glass substrate at the bottom of the corresponding barrier each for a length of 40 .mu.m or more as measured along the width direction of the discharge chamber, said discharge electrodes being exposed for a width of less than 50 percent of a pitch of said electrodes from one another, said exposed surface being a top surface of said discharge electrodes facing and spaced from said dielectric sheet, each of said barrier ribs being of a height of approximately 200 .mu.m, each of said discharge electrodes being of a width of approximately 210 .mu.m.
- 8. A plasma-addressed display device, comprising:
- a first substrate having a plurality of data electrodes arranged in parallel to each other;
- a dielectric sheet disposed face-to-face to the first substrate to form a display chamber therebetween;
- a second substrate spaced from said dielectric sheet to form a discharge space therebetween;
- a plurality of discharge electrodes on said second substrate on a surface facing said dielectric sheet, said discharge electrodes being elongated in a direction substantially perpendicular to said data electrodes and being parallel to one another, said discharge electrode having top surfaces facing said dielectric sheet and spaced from said dielectric sheet, said top surfaces of said discharge electrodes each being of a predetermined width, said discharge electrodes being spaced from one another by a predetermined pitch; and
- a plurality of barrier ribs extending parallel to one another between said dielectric sheet and said top surface of said discharge electrodes to define discharge channels, said barrier ribs being elongated in a same direction as said discharge electrodes, each of said barrier ribs being on a corresponding one of said discharge electrodes, said barrier ribs covering a portion of said top surfaces, said barrier ribs being of a lesser width than said predetermined width of said discharge electrodes so that exposed portions of said top surfaces are free of said barrier ribs and exposed in said discharge chamber for electrical discharge on both sides of said barrier ribs, said exposed portions being less than 50 percent of said predetermined pitch, said exposed portion of each of said discharge electrodes being at least 40 .mu.m in a width direction on each side of said barrier to ribs.
