Vacuum fluorescent display with driver IC

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 installed above the display unit;
• a grid disposed between the filamentary cathodes and the display unit;
• an IC mounted on the anode substrate within an end cooling area of the filamentary cathodes and adapted to drive the display unit;
• and
• a filament support for shielding the IC and supporting an end part of the filamentary cathodes;
• wherein the phosphor layer is excited and caused to emit light by irradiating the phosphor layer with electrons generated from the filamentary cathodes;
• the vacuum fluorescent display with a driver IC characterized in that 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, a depression is provided to a surface of the filament support disposed below the end cooling area of the filamentary cathodes;
• the filamentary cathodes and the surface of the filament support are prevented from making contact;
• and the distance between the filamentary cathodes and the phosphor layer is reduced.
