Abstract
In a liquid crystal reflecting device comprising a cell () formed by two cell walls () spaced apart by spacers () to contain a layer () of a liquid crystal material, electrode structures () on the inner faces of the walls, and a surface alignment on one or both walls to align the liquid crystal material, a diffuse specular reflector is provided by a mirror base layer () formed by at least two different materials that are at least partly immiscible relative to one another forming a rough surface onto which a reflective layer () is coated. The mirror base layer () is formed by at least two different polymer and/or monomer materials that are at least partly immiscible relative to one another. The reflector layer () may be a single sheet, formed into a plurality of separate reflector elements, or patterned into electrodes.
