とする螢光表示管。 A vacuum container is formed by sealing an envelope on the substrate,
A cathode support for supporting the cathode in a fluorescent display tube having a structure in which shielding is performed by applying a potential of a cathode mounted on a substrate in the vacuum container to a transparent conductive film attached to an inner surface of the envelope. A getter is attached to one side of the body, and a part of the wiring layer formed on the substrate from which the cathode support is to be drawn out of the vacuum container or a conductive layer directly connected to the cathode support is inside the vacuum container. By exposing a part of the wiring layer or the conductor layer to the transparent conductive film on the inner surface of the envelope, conduction is established by the getter coating generated by the flashing of the getter. A fluorescent display tube characterized in that:
