Abstract
High resolution color displays for field emission displays are formed by applying a grille to a screen layer, the grille having a set of holes formed therein exposing areas of the screen layer. A layer of photoresist is applied to the grille and the exposed areas of the screen layer, whereby a plurality of photoresist-covered screen layer areas are defined. One set of the plurality of photoresist-covered screen layer areas is fixed, whereby a fixed set and an unfixed set are defined. The photoresist is removed from the unfixed set and a light emitting substance is deposited on the exposed screen layer area. The fixed set of photoresist is plasma etched.
