Abstract:
1. A method of manufacturing a cell wall assembly for an electro-optic display device with greyscale capability, the method comprising: forming on a substantially planar surface of a transfer carrier, at least one dielectric structure, wherein said surface of said transfer carrier is electrically conductive, forming on said at least one dielectric structure at least one electrode structure; wherein said dielectric structure extends in a direction perpendicular to said surface by a distance which varies substantially within the area of the or each electrode structure; adhering said at least one electrode structure to a major surface of a substrate of glass or a plastics material; removing the transfer carrier thereby resulting in a cell wall assembly with a substantially planar surface; and forming at least one busbar on said surface of said transfer carrier and within said dielectric structure by electro-deposition of a metal.
