DYNAMIC-DRIVE FLUORESCENT DISPLAY TUBE

PROBLEM TO BE SOLVED: To provide a dynamic-drive fluorescent display tube that can effectively prevent leakage emission and simplify wiring structure. SOLUTION: This dynamic-drive fluorescent display tube contains a pair of substrates 4 and 6, a side glass 2 located between the substrates, wirings 10 and 30 provided on at least one of the substrates so as to make electrical connection in the interior of the fluorescent display tube, an insulating layer 16 to prevent unnecessary current flowing among the wiring, filaments 8 receiving current from the wiring to emit thermal electrons, fluorescent substance 12 that gives light emission by bombardment of the thermal electrons, and electronconductive partitions 14 that is formed at the prescribed height of the fluorescent substance and that control emission of the fluorescent substance by accelerating or stopping the thermal electrons emitted from the filament by receiving current from the wire.
