Abstract: An indicator display tube in which indicator electrode units, each consisting of anode and cathode segments, lie in the same plane and in which all of the cathode segments are simultaneously energized and the anode segments are energized on a time sequential basis in such a manner that only the indicator electrode unit having its anode segments energized will glow at a particular time. The cathode segments of each indicator unit are connected in parallel. The indicator display tube has barrier segments for preventing accidental discharge of adjacent indicator electrode units which would produce erroneous message displays. At least the cathode but preferably all of the segments are formed of a silver paste coated with nickel. The base material on which the silver paste is coated is glass. This arrangement prevents sputtering.
