Title: Manufacturing method of plasma display panel
Inventor: WATANABE HIROSHI
IPC: H01J11/38
Filed: 2000-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a plasma display panel overcoming the problem of the breakdown voltage of a dielectric glass layer. SOLUTION: As shown in figure 6 (c), the glass particles after receiving the surface melt-treatment become almost spheres as the edged parts of the glass particles roughly crushed by a crusher were smoothed down. As the use of such molten glass powders brings a uniform wetness on the glass particle surfaces, the binder 64 uniformly sticks to the surfaces of the glass particles 63 at a stage when glass powders are printed. As a result, it is also unlikely to cause that the combustion gas remains in the dielectric glass layer as air bubbles. As given in figure 6 (d) and compared with figure 6 (b), the number of air bubbles in the completed dielectric glass layer is considerably small.
