Claims
- 1. A channel plate structure for a flat display, said channel plate structure comprising a dielectric substrate, essentially parallel, spaced flanking wall portions directly contacting a surface of the substrate and positioned, with said surface of the substrate to define elongated channels therebetween, a pair of spaced electrode surfaces provided in each of the channels and a thin dielectric sheet-like member provided atop the flanking wall portions, characterized in that:a) the flanking wall portions are parts of an integral dielectric sheet, b) the surface of the substrate directly contacted by the flanking wall portions is an ion-containing surface.
- 2. A channel plate structure as claimed in claim 1, wherein the thin dielectric sheet-like member, the dielectric sheet, and the substrate are constituted of glass.
- 3. A channel plate structure as claimed in claim 1, wherein the flanking wall portions are joined at their periphery by an integral border region.
- 4. A channel plate structure as claimed in claim 1, wherein the flanking wall portions are laterally spaced apart by etched slots.
- 5. A plasma channel plate structure for use in a PALC display device comprising elongated channels, each channel provided with a pair of spaced electrodes and filled with a plasma-containing atmosphere, on an ion-containing surface of a substantially transparent dielectric substrate, characterized in that:a) on the ion-containing surface is a plurality of deposited spaced electrically conductive electrode layer portions, b) each of the channels is defined by a pair of, essentially parallel, spaced wall portions directly contacting areas of the ion-containing surface free of the electrode layer portions, said wall portions being part of a spacer plate mounted over the ion-containing surface, and a portion of the ion-containing surface provided with a pair of the electrode layer portions and within the pair of wall portions.
