Abstract:
A liquid crystal display comprising a liquid crystal layer formed between two conductive substrates, wherein at least one of said substrates is transparent, said liquid crystal layer including a network of polymerized monomer walls respectively separating a plurality of liquid crystal portions from one another, wherein each of said liquid crystal portions (i) is formed of a material that is substantially non-soluble with said monomer at normal temperatures (ii) is selected from the group consisting of cholesteric liquid crystal, chiral nematic liquid crystal or a mixture thereof, and (iii) is respectively roughly pillar-like in shape so as to define a cross-section parallel to said substrates that has a polygonal or a closed curve periphery and a minimum cross-sectional dimension measured by vernier calipers of at least about 5 &mgr;m and a maximum cross-sectional dimension measured by vernier calipers of not more than about 100 &mgr;m , and wherein said liquid crystal layer occupies 90% or more of the entire liquid crystal layer.
