PURPOSE: A dynamic drive type vacuum fluorescent tube is provided to effectively avoid luminescence leakage, and simplify wiring structure. CONSTITUTION: A dynamic drive type vacuum fluorescent tube comprises a front plate(4), a rear plate(6) sealed with the front plate(4) by side glasses(2), many filaments(8), wires(10), fluorescent material(12), conductive barrier ribs(14), and an insulating layer(16). The filaments(8) traverse the inside between the front plate(4) and the rear plate(6). The wires(10) electrically connect inside the vacuum fluorescent tube. The fluorescent material(12) forms on the surface of the wires(10) to form a display pattern. Each of the conductive barrier ribs(14) is formed around the fluorescent material(12) by a height from the top side of the fluorescent material(12). The insulating layer(16) prevents the wires(10) from being unnecessarily conducted. The wires(10) includes an anode electrode and a grid electrode.
