Abstract:
A gas discharge panel comprising:a pair of substrates defining an electric discharge space therebetween;a plurality of barrier ribs arranged parallel to each other in a striped configuration within a display area in the electric discharge space for partitioning the electric discharge space;a sealing member provided between the pair of substrates on the periphery thereof; andat least two gas flow barriers,wherein one of the substrates has a first vent hole and a second vent hole provided in a peripheral portion thereof for intercommunication between an inside and outside of the panel, andthe at least two gas flow barriers are provided in peripheral spaces between the sealing member and the barrier ribs located on opposite sides of an arrangement of the barrier ribs and positioned relative to the sealing member and the barrier ribs so that a gas introduced from the first vent hole is restricted from flowing into the peripheral spaces and instead flows through inter-rib spaces defined between adjacent pairs of barrier ribs and is expelled from the second vent hole.
