Abstract

PURPOSE:To simplify the structure and to perform the indication by driving in line sequential scanning system, by arranging grid electrode group having new control function in the space between the cathode and anode. CONSTITUTION:A vacuum container 11 is comprised of a planar substrate 11a and a convex glass board 11b. An electron emission subsistance is coatecd on the surface of a tungsten wire filament cathode 12. An anode 12 common to the entire surface is made of tin oxide. A light emission fluorescent material 14 is coated in dot-matrix on the surface of the anode 13. A glass spacer 15 provided with holes in dot-matrix in correspondence with the dot of the fluorescent material 14 is arranged in the space between the cathode 12 and the anode 13, while furthermore first grid electrode group 16 and second grid electrode group 17 are arranged perpendicularly while holding the glass spacer 15 between them.
