Abstract
An effective non-specular reflector, for use in a Liquid Crystal Display, is formed by first coating a substrate with a two component solution. One component hardens when heated or when exposed to ultraviolet light (optionally through a mask) while the other component remains liquid. The result is a solid layer in which are dispersed multiple liquid regions, some of which break the surface where they are easily removed, leaving behind a roughened surface. Once a high reflectance metal has been deposited onto this surface it becomes an effective nonspecular reflector. Examples of materials for use as the two components are given.
