Abstract
Gas discharge display device having a vacuum-tight envelope with a front and back plate. A control unit divides the interior of the envelope filled with gas into a back and front space. The back space has at least one plasma cathode and at least one plasma anode. The front plate carries a cathodoluminescent layer and a layer electrode. The control unit contains at least one electrode plane extending parallel to the wall plates, with at least one conductor. In operation a gas discharge burns between the plasma electrodes. The distance between the post-acceleration anode and cathode is small such that no gas discharge is ignited in the post-acceleration space. The post-acceleration cathode is coated with an implantation protection layer of a high-melting metal to maintain the operating voltage constant under continuous load.
