ABSTRACT:
A fluorescent display tube including: (a) a substrate having a display surface; (b) anodes formed on the display surface of the substrate, and spaced apart each other; (c) cathodes capable of generating electrons; (d) fluorescent layers each of which is fixed to a corresponding one of the anodes; (e) a rib formed on the display surface of the substrate so as to surround a periphery of each of the fluorescent layers; and (f) a control electrode fixed to an upper end face of the rib, and consisting of a plurality of sections which are spaced apart each other; wherein the fluorescent layers are selectively activated by the control electrode, so as to be struck by the electrons generated by the cathodes, for emitting light, wherein the rib includes continuous wall portions continuously extending along respective boundaries each of which is located between a corresponding pair of the anodes which are adjacent to each other, such that each pair of the anodes are electrically insulated from each other, and wherein the continuous wall portions include portions each of which extends between a corresponding pair of the sections of the control electrode which are adjacent to each other and which are spaced apart from each other.
