Abstract
Abstract A flat gas discharge panel comprising two opposed glass plates sealed with a space for gas therebetween and having a plurality of first and second electrodes, respectively mounted on opposite plates in a matrix fashion and further including a plurality of parallel insulator ribs which intersect the first electrodes at right angles and further provide physical separation between the glass plates and the adjacent discharge segments. A plurality of parallel barrier electrodes are mounted on one of the plates in alignment with the insulator ribs so as to maintain the glow from an illuminated section isolated from adjacent sections, and at least two different phosphors for emitting different color lights are mounted in the sections at different positions.
