There is disclosed a positive column gas discharge plasma display device comprising one or more ionizable gas filled elongated Plasma-tubes. The display may be a dual substrate or a single substrate device. One or more substrates may be of a flexible material. The ionizable gas produces photons in the UV, IR, and/or visible range during gas discharge. The photons may excite one or more luminescent materials located on or in close proximity to one or more Plasma-tubes. The plasma display device may contain at least one Plasma-shell filled with an ionizable gas that produces photons in the UV, IR, and/or visible range during gas discharge. Plasma-shell includes Plasma-disc, Plasma-dome and Plasma-sphere.
