Liquid crystal prepolymer composition and liquid crystal display device using the same

A liquid crystal display device comprising a pair of support materials, and a liquid crystal/polymer composition held between said support materials, said liquid crystal/polymer composition comprising a liquid crystal component and a polymer composition, with phase separation into said liquid crystal component and said polymer composition, which is formed by polymerizing a liquid crystal/prepolymer composition which comprises a liquid crystal component, a prepolymer composition and a photopolymerization initiator, said liquid crystal/prepolymer composition, when polymerized, being capable of inducing said phase separation, said prepolymer composition consisting essentially of (a) monofunctional acrylate component having one double bond, with an HLB value of 3.2 to 5.5;

• and (b) a bifunctional acrylate component having two double bonds, with an HLB value of 3.5 to 11, wherein the amount of said monofunctional acrylate component is present in an amount of 20 to 80 wt. % of the total weight of said prepolymer composition.
