Abstract
Methods of forming plasma addressed liquid crystal display ribs are disclosed. An exemplary method includes introducing a glass paste which includes a curable medium into cavities formed in an intaglio collector to define rib structures, which are from the collector to a surface of the substrate, and removing the curable medium from the rib structures on the substrate surface to generate pores in the rib structures. The substrate having rib structures is then dipped into a solution containing an opaque pigment which is absorbed into the rib structure. Another method 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.
