Abstract
Plasma addressed liquid crystal display ribs are formed by a method which includes forming a temporary mask on portions of a surface of a substrate, depositing a layer of a glass paste having a curable medium and at least one pigment blended therein over the substrate and temporary mask, micro-molding rib structures from the glass paste on the substrate surface in areas between the masked sections, removing any residual layer of paste material present on the temporary mask, removing the temporary mask from the substrate, and firing the substrate with micro-molded rib structures thereon.
