Abstract:
1. A method of producing a rear panel for plasma display comprising, on a substrate, approximately stripe-like address electrodes, a dielectric layer covering said address electrode, and a lattice-like barrier rib positioned on said dielectric layer and consisting of main barrier ribs which are nearly parallel to said address electrodes and auxiliary barrier ribs intersecting said main barrier ribs, wherein a bottom width of an auxiliary barrier rib intersecting a main barrier rib positioned at an outermost portion in a nondisplay area to the right and left of the display area, is 0.3 to 1.0 times a bottom width of said main barrier rib positioned at the outermost portion in the nondisplay areas on the right and left of the display area, the method comprising applying a photosensitive glass paste consisting of an inorganic component mainly comprising glass powder and an organic component containing a photosensitive organic substance over a substrate provided with either address electrodes or precursors thereof and either a dielectric layer or a precursor thereof, followed by exposing using a photomask designed for forming precursors of auxiliary barrier rib, further coating with the photosensitive glass paste, exposing using a photomask designed for forming precursors of main barrier rib, and developing to form a precursor of barrier rib consisting of precursors of main barrier rib and precursors of auxiliary barrier rib, which is then fired to form barrier ribs, wherein the bottom width of the precursor of auxiliary barrier rib intersecting the precursor of main barrier rib positioned at the outermost portion in the nondisplay areas on the right and the left of the display area is 0.3 to 1.0 times the bottom width of said precursor of main barrier rib positioned at the outermost portion in the nondisplay areas on the right and the left of the display area.
