PURPOSE:To provide a gas electric discharge type display with high brightness and to extend the life of the display by means of the sputter preventing effect of mercury by providing partition walls parallel to cathodes at each cathode block, and performing scanning in such a manner that discharge cells in the same block do not simultaneously enter a period of selection. CONSTITUTION:A cathode group 11 consisting of cathodes K1, K2,... are installed on a back panel 1 and spaces among the cathodes are partitioned into discharge spaces by a partition wall group 13 consisting of long strip. partition walls W1, W2,... each of which orthogonally intersects the cathode group 11. The cathode group 11 are bound into blocks each consisting of the L number of cathodes and block partition walls 14 parallel to the cathodes are installed between the blocks. On each partition wall group an anode group 12 consisting of anodes A1, A2,... and a glass plate 4 to which phosphor 5 is applied and baked are brought into sealing contact with each other in such a manner that the anode group 12 and the cathode group 11 orthogonally intersect and are opposite each other, and discharge cells 6 are formed at points of intersection of the groups 11,12. Thereafter the whole display is hermetically sealed and rare gas and a small amount of mercury are sealed therein. The cathode group 11 are divided into (n) blocks and scanning is performed at each block so that two cathodes in the same block do not cause display discharge simultaneously.
