Abstract

Abstract The gas discharge panel disclosed in this application is composed of parallel electrode groups, a dielectric layer for covering the electrodes and a gas discharge space or gap in which a firing spot is produced through the discharge space via the dielectric layer when an electric signal is applied to the electrode pairs. The above-mentioned dielectric layers provide a suppression layer having a predetermined pattern which partially decreases leakage from the discharge field into the gas discharge space, that is, decreases the gas discharge in a position where a gas discharge is not required. In the gas discharge panel having a function of self-shift, this suppression layer has the form of a metallic strip, positioned at a right angle to these electrodes, or of a dielectric strip having a high dielectric constant, and constitutes a shift channel for the gas discharge spot. Further this supression layer is useful for carrying out a read-only memory type gas discharge by providing a predetermined pattern.
