Abstract
To provide an AC driving type matrix plasma discharge display device which can reduce power consumption and a fabricating method of the same. First and second substrates 1 and 2 are disposed so as to oppose each other, and a first electrode group 21, which is constituted so that a plurality of first discharge electrodes 11 are disposed, is formed on the first substrate 1, and a second electrode group 21, which is constituted so that a plurality of second discharge electrodes 12 are disposed, is formed on the second substrate. A plasma discharge display is executed by mainly utilizing a cathode glow discharge.
Claims8
A flat display device, comprising:
- first and second substrates are disposed so as to oppose each other;
- a first electrode group which is constituted so that a plurality of first electrodes are disposed is formed as one discharge electrode on said first substrate;
- a second electrode group which is constituted so that a plurality of second electrodes are disposed is formed as the other discharge electrode on said second substrate;
- and mainly,
- a plasma discharge display is executed by a cathode glow discharge,
- wherein said first electrodes are disposed with their main extended direction defined as a first direction along a surface of said first substrate;
- a plurality of projecting walls which are extended to a second direction crossing the first direction are disposed in parallel on said second substrate along a surface of said second substrate;
- and
- said second electrodes are formed respectively on top portions of at least every other projecting walls of said projecting walls.
A method of fabricating a flat display device, characterized by comprising:
- the step of forming a first electrode group, which is constituted so that a plurality of first electrodes are disposed with their mainly extended direction defined as a first direction along a surface of a first substrate, on said first substrate;
- the step of forming grid-state projecting bars which are constituted by projecting bar portions, which are extended to a direction crossing said first electrodes and arranged in parallel at predetermined spaces, and intersecting projecting bar portions, which cross said projecting bar portions and are extended along between said first electrodes;
- the step of forming a projecting wall group, which is constituted so that a plurality of projecting walls extending to a second direction along a surface of said second substrate are disposed in parallel, on said second substrate;
- the step of flying an electroconductive material onto said projecting walls of said second substrate from a diagonally upper direction crossing the second direction and depositing the electroconductive material selectively to top portions of said projecting walls, and side walls in the neighborhood of said projecting walls so as to form second electrodes by the electroconductive material formed on the top portions of the required projecting walls;
- and
- the step of applying a fluorescent layer between said projecting walls,
- wherein said first and second substrates are made to oppose each other so that said first and second directions cross one another, and said projecting walls and said intersecting projecting bar portions at least work together so that spacing between said second electrodes and said first electrodes is set to predetermined spacing.
