Claims

[Scope of utility model registration request]

A wiring layer having a predetermined wiring pattern is provided on the anode substrate forming the fluorescent display section, and the grid is connected to the wiring layer through each grid connection portion and an insulating layer formed to cover the wiring layer. In a fluorescent display tube having a structure in which electrodes are connected by conductive paste, a layer is placed on the anode substrate between each of the grid connections with respect to the fluorescent display pattern so as to prevent the conductive paste from flowing. A fluorescent display tube characterized by being provided with an insulating protrusion having a curved mouth shape at the periphery.
