Abstract
The distance between filamentary cathodes and a phosphor on an anode substrate can be reduced by shortening the distance between the filamentary cathodes and a grid. To obtain high luminance without loss of display quality, the present invention provides a vacuum fluorescent display () with a driver IC, comprising a display unit () provided with a phosphor layer on an anode substrate (), a plurality of filamentary cathodes (), a grid (), a driver IC (), and a filament support () for shielding the IC and supporting an end part of the filamentary cathodes. The end part of the filamentary cathodes is fixed to one short side of the vacuum fluorescent display at a long side of the filament support. Depressions are provided to a surface of the filament support, or slits are provided to the filament support.
