ABSTRACT:
A manufacturing method for a vacuum fluorescent display is performed by the steps of dividing a substrate into a plurality of areas, and sequentially forming a signal line, an insulating layer, and a segment electrode on each area, arranging common wiring layers with a predetermined distance therebetween on the substrate to be electrically connected to all signal lines formed on the substrate, submerging the substrate into a container filled with a dispersed fluorescent material, and settling the fluorescent material on the segment electrode by applying power to the common wiring layers, and forming rear plates by cutting the substrate having the fluorescent material settled thereon into the plurality of individual areas. A separate settling jig is not required, and cost for the formation of the settling jig and manpower for its handling can be reduced, so that productivity is enhanced.
