Abstract
A channel member for a PALC panel is fabricated from a substrate of hard transparent material by forming a layer of conductive material over an upper surface of the substrate, forming a layer of insulating material over the layer of conductive material, removing the layer of insulating material in accordance with a predetermined spatial pattern so as to expose predetermined portions of the layer of conductive material, and removing exposed portions of the layer of conductive material by erosion until parts of the upper surface of the substrate are exposed.
