Claims

[Scope of utility model registration request]

A fluorescent display that includes an anode having a phosphor in an outer wall formed by sealing an anode substrate and a top plate, spacers arranged at regular intervals, a grid for current control, and a filament that emits thermoelectrons. In the tube, the distance between the insulating layer surface of the anode substrate and the spacer grid frame is made constant. A fluorescent display tube characterized in that a frit sealing material is spread between an anode substrate and a spacer grid frame and fixed with the frit sealing material.
