Abstract
A fluorescent display tube is disclosed. In the fluorescent display tube, linear members, such as, for example, wire grids and filament are sustained in a predetermined height, while both ends of each linear member are welded on a metal layer by ultrasonic. The fluorescent display tube includes a metal spacer for fixing the linear member and holding the linear members in an elevated position so that the dead space within the fluorescent display is reduced. The linear members are bonded on an aluminum thin films formed on the glass substrateby way of the aluminum spacer. The aluminum spacer sustains the linear members in a predetermined height. Aluminum spacer acts as a member for fixing the linear member and as a height level holding member.
