LIQUID CRYSTAL COMPOSITION, POLYMER/LIQUID CRYSTAL COMPOSITE, LIQUID CRYSTAL ELEMENT, AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
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). In (G1), X represents a mesogenic skeleton; Y represents an oxyalkylene group (including carbon and oxygen), and includes hydrogen or fluorine; and Z1 and Z2 individually represent an acryloyl group or a methacryloyl group.
