Claims

[Scope of utility model registration request]

A fluorescent display tube in which thermoelectrons emitted from a cathode filament collide with one or more anode patterns coated with a fluorescent material on an insulating substrate to cause the fluorescent material to emit light, the structure of the fluorescent display tube The wiring conductor and insulating layer, which are the elements, are made of a translucent material, and light is applied to the back side of the fluorescent display tube through a filter or film with colored characters, figures, etc. drawn on it. A fluorescent display tube that can display colors, characters, graphics, etc. behind the display pattern of the fluorescent layer.
