Abstract:
A substrate for a plasma display panel comprising:a) a transparent substrate; b) at least one pair of electrodes made of opaque conductive silver (Ag), formed by applying and sintering a paste of said silver, and arranged on the side of one main surface of said transparent substrate, each electrode having a base portion and a projecting portion which is coupled with said base portion and projects from said base portion along said main surface, each of said projecting portions including: 1) a first portion coupled with said base portion to extend in a projecting direction of said projecting portion, and 2) a second portion coupled with an end of said first portion separated from said base portion; and c) an underlayer arranged between said transparent substrate and said electrodes, in contact with said electrodes, and formed of a transparent dielectric substance formed at a temperature below the softening point of said transparent substrate; wherein said second portions of said projecting portions of said electrodes face each other to form a discharge gap between said projecting portions; wherein said at least one pair of electrodes includes a plurality of pairs of electrodes arranged at a prescribed pitch in a projecting direction of said projecting portion, and bpâˆ’gâˆ’115)/2.42 wherein:p (&mgr;m) represents said prescribed pitch, and b (&mgr;m) and g (em) represent respective lengths of said projecting portion and of said discharge gap in said projecting direction.
