PURPOSE: A fluorescent display tube is provided to reduce the thermal effect of the parts and simplify the manufacturing process, thereby improving the productivity. CONSTITUTION: A fluorescent display tube comprises a rear surface substrate(20), a front surface substrate(22), a side glass(24), a cathode(30), an anode(26), a grid(40), and a plurality of lead wires(43). The cathode(30) is formed on the inner surface of the rear surface substrate(20). The anode(26) is formed on the front surface substrate(22), and a fluorescent body is coated on the anode(26). The grid(40) is installed on the front surface substrate(22), and is located between the cathode(30) and the anode(26). The lead wires(42) applies an electric power to the cathode(30), the anode(26), and the grid(40).
