Abstract

PURPOSE:To surely suppress a malfunction of a tube deriving from a change of space between a grid and anode or filament, by using a mesh construction having a patterned portion of lines in which a curved line or bent line or the both are used together. CONSTITUTION:On an electrode provided on a base plate made of, for instance, glass in a vacuum air-tight vessel, display patterns such as numeric character or code, graphic figure and the like are formed by a fluorescent material, and a fluorescent display is performed by controlling an electron emitted from a single or plurality of filaments by a grid and permitting its impact on the fluorescent material. At least one of the sides of a unit mesh in the grid is shaped in such a line that a curved line or bent line or the both are used together.
