Abstract: A gas discharge display panel which provides sufficient contrast and good accuracy and is high in yield. When a voltage is applied to auxiliary discharge electrodes, auxiliary discharge occurs in an auxiliary discharge space and excited charged particles communicate with a main discharge space through a priming path made in a discharge space separation bulkhead. In this state, when an alternating voltage is applied between bus electrodes on a front substrate, main discharge occurs in the main discharge space, causing Xe atoms in the sealed gas to generate ultraviolet rays, causing a phosphor to emit light. However, since the auxiliary discharge is shielded by a bulkhead and a barrier rib, the phosphor does not emit light when only auxiliary discharge occurs.

Abstract translation: 气体放电显示面板，其提供足够的对比度和良好的精度并且产量高。 当向辅助放电电极施加电压时，在辅助放电空间中发生辅助放电，并且激发的带电粒子通过在放电空间分隔隔板中形成的起动路径与主放电空间连通。 在这种状态下，当在前基板上的总线电极之间施加交流电压时，在主放电空间发生主放电，导致密封气体中的Xe原子产生紫外线，使荧光体发光。 然而，由于辅助放电由隔板和隔板屏蔽，所以当仅发生辅助放电时，荧光体不发光。
