Abstract
A liquid crystal composition with which generation of an alignment defect in a polymer/liquid crystal composite exhibiting a polymer-stabilized blue phase can be reduced is provided. The liquid crystal composition includes a liquid crystal material exhibiting a blue phase; and a liquid crystalline monomer. In the liquid crystalline monomer, the chain length (the sum of carbon atoms and oxygen atoms) of an oxyalkylene group represented as Y in the following general formula (G1) is n (2≦n≦11). The liquid crystalline monomer has a lower phase transition temperature from a nematic phase to an isotropic phase (TNI) than liquid crystalline monomers including the oxyalkylene groups whose chain lengths are (n−1) and (n+1).
