Claims

[Scope of utility model registration request]

The display element is a display pattern section in which display segments are arranged in a dot-to-tomato pattern from an anode and a phosphor coated on the anode, and the display pattern section is arranged in a plurality of digits, and the display pattern for each digit is used as a display element. In a fluorescent display tube having a structure in which a control grid is arranged corresponding to each display pattern section, each of the display pattern sections is configured such that each anode is connected only to anodes in a row near the adjacent digits divided by each control grid. A fluorescent display tube characterized in that the fluorescent display tube is larger than the area of the fluorescent body and protrudes toward the adjacent girder side.
