PROBLEM TO BE SOLVED: To provide a polymer / liquid crystal composite material exhibiting a large electric birefringence in a wide temperature range. Also provided is a polymer / liquid crystal composite material in which birefringence does not remain after electric field removal. Provide liquid crystal materials with excellent long-term reliability. An optically isotropic liquid crystal phase that exhibits an optically isotropic liquid crystal phase in a temperature range of 5 ° C. or higher in a temperature rising process and includes a polymer and a liquid crystal material that does not exhibit a nematic phase. A polymer / liquid crystal composite material used for an element driven in a liquid crystal phase. [Selection figure] None |
