Abstract
A liquid crystal/prepolymer composition which is composed of a liquid crystal component, a prepolymer composition and a polymerization initiator, the liquid crystal/prepolymer composition, when polymerized, being capable of causing phase separation into the liquid crystal and a polymer, the prepolymer composition containing a monofunctional acrylate component having one double bond, with an HLB value of 2.5 to 7.0; and a bifunctional acrylate component having two double bonds, with an HLB value of 3.5 to 11. In addition, there is also disclosed a liquid crystal display device composed of a pair of support materials and a liquid crystal/polymer composition held between the support materials, with the phase separation into the liquid crystal component and the polymer composition, which is formed by polymerizing the above-mentioned liquid crystal/prepolymer composition.
