Abstract

PURPOSE: To avoid defective connection between the anode button and the metal back layer, by coating the conductive material on the anode button before the face plate and the funnel are welded.
CONSTITUTION: Before welding the face plate 9 at the funnel section 4 of glass bulb, the conductive material (for example, graphite) including glass frit is coated on the upper part of the anode button 7 from the greater opening of the funnel 4 so that the unevenness of the circumference of the anode button 7 can be eliminated. After that, the face plate 9 is welded on the funnel section 4. Since the conductive material includes the glass flit, it is strongly sticked to the anode button 7 at welding. Then, the Aquadag film 6 is coated inside the glass bulb 1 obtained by immersing it into the dag liquid 11. After that, the metal back layer is evaporated inside the face plate 9.
