Patent ID: 7351506

Claim:
A bistable polymer dispersed liquid crystal display comprising: at least one substrate; a polymerized liquid crystal dispersion disposed on said at least one substrate, said dispersion comprising a plurality of domains, wherein said liquid crystal dispersion comprises at least a non-polymerizable liquid crystal material, a mixture of polymerizable monomers, and a polymerization initiator, wherein said polymerizable monomers comprise one or more polymerizable groups; and wherein a size of each said domain is controlled by a functionality of said polymerizable monomers defined by F = ∑ x = 1 n ⁢ ⁢ f x * ⁢ M x / ∑ x = 1 n ⁢ ⁢ M x , wherein F is functionality, f x is the number of polymerizable groups, M x is a mass fraction of the dispersion material, and n is the number of polymerizable monomers in said dispersion.
