Abstract
A single substrate AC and/or DC gas discharge (plasma) display device with hollow shells containing ionizable gas at a predetermined pressure, each shell being positioned on the surface of the substrate or within a substrate cavity, well, or hollow. Each shell is in electrical contact with at least one electrode, typically two, three, or more electrodes. The AC or DC gas discharge within each shell emits photons in the visible and/or invisible range. In one embodiment, photons from the gas discharge within a shell excite a luminescent substance or material such as a phosphor that emits photons in the visible and/or invisible spectrum. The shell may contain the luminescent substance or the substance may be located separately from, but in close proximity to the shell.
