摘要:
A gas discharge display panel adapted for effecting display by a plurality of gas discharge elements arranged in a matrix has a cathode formed by coating the substrate surface with a (100) preferred film of a rare earth hexaboride such as LaB.sub.6. The gas discharge display panel can be driven at relatively low voltage.
