Abstract
A vacuum fluorescent display includes a display portion, filament cathode, grid, and a pair of filament support members. The display portion is arranged on a substrate and has an anode coated with a phosphor material in accordance with a pattern to be displayed. The filament cathode is applied above the anode of the display portion to be separate from the anode. The grid is arranged between the anode of the display portion and the filament cathode, and cooperates with the corresponding anode to display a predetermined pattern. The pair of filament support members are connected to an outside and extend the filament cathode. Part of the filament support members is clamped between a front glass plate and glass spacer and is extracted to outside.
