PURPOSE: A fluorescence display tube of double sided luminous type is provide to improve the degree of freedom on the wires and to grasp easily a getter location. CONSTITUTION: A fluorescence display tube of double sided luminous type comprises a side glass(6) for locating between a front substrate(2) and a backside substrate(14), a fluorescent substrate(18) applied on the surface of an anode electrode, a cathode(24) which applies it with a power supply to emit thermoelectron, a grid electrode(26) which accelerates the thermoelectron emitted from the cathode and then is conflicted to the fluorescent substrate, a getter supporter which is fixed to one of the substance, a getter instrument(28) fixed to the getter supporter, and a getter location display means(30c) which can identify a location of the getter instrument.
