Claims

[Scope of utility model registration request]

A display pattern is formed by coating a phosphor on a transparent anode substrate inside a sealed container, and the electrons emitted from the filament are
In a fluorescent display tube having a structure in which acceleration is controlled by an electric field formed by a potential applied to a grid, the phosphor is impacted to emit light, and the display is observed from the surface opposite to the electrode-formed surface of the transparent anode substrate. A fluorescent display tube characterized in that at least the display surface side of the grid is made of a glossy material.
