Claims

[Scope of utility model registration request]

An anode coated with a phosphor layer is arranged in accordance with a display pattern on a substrate constituting a part of a vacuum-tight envelope, and a plurality of anodes are divided according to the display pattern of the anode. In a fluorescent display tube, which has a control electrode of 1 and 2 and which produces a desired luminescent display by selectively bombarding the anode with electrons emitted from the cathode, the inner surface of the envelope facing the control electrode has various A plurality of conductive films are electrically divided and formed corresponding to the control electrodes, and each conductive film and the corresponding control electrode are electrically connected to each other by a connecting terminal. Fluorescent display tube.
