Claims

[Scope of utility model registration request]

a transparent conductive anode on a transparent substrate; a phosphor is coated on the anode to form a display pattern; electrons emitted from the filament are caused to collide with the phosphor to produce a light-emitting display; and the transparent glass anode 1. A fluorescent display tube having a structure in which a luminescent display is observed from a surface opposite to an electrode-formed surface of a substrate, characterized in that an independent fixed display is provided on the inner or outer surface of the transparent substrate.
