Abstract
In a driving IC-incorporated fluorescent display device, a filament end-supporting member including a structure which has a short distance between a filament and an anode substrate and is not compromised to shielding effect of the driving IC is provided. An end portion of the filament is sandwiched between a tabular support which is attached to a tabular portion of a retainer plate and a ribbon, and the ribbon is fixed to the support by spot welding. The support consists of a slit. The filament is opposed to the slit and extends to longitudinal direction of the slit. The opposite side of the filament of the slit is closed by the retainer plate.
