光表示管。 A fluorescent display tube has a structure in which a display pattern is formed using a fluorescent material on an insulating substrate constituting an airtight container, and electrons emitted from a filament impact the fluorescent material to cause it to emit light while observing the display. A fluorescent display tube characterized in that a light-transmitting layer with a low refractive index is provided on the front, back, or both sides of a side cover glass.
