The present invention intends to provide a manufacturing method for a
plasma display panel, so as to overcome problems associated with a
withstanding voltage of a dielectric glass layer. Glass particles have
angular shapes after grinding with a grinder, but as the surface of them
has been melted, they are converted into spheroids. Those glass particles
can get wet evenly, so that a binder evenly adheres to the surface of a
glass particle when a glass paste including the glass particles is applied
to the surface of a substrate. In this case, there is a scarce possibility
for a gas, generated by baking the binder, to remain in the form of
bubbles in a formed dielectric glass layer. There are fewer bubbles
remaining in a completed dielectric glass layer than in a dielectric glass
layer than in a glass layer made from angular glass particles.
