摘要:
A liquid crystal composition for forming a polymer/liquid crystal composite in which disorder of an orientation state is reduced is provided. The liquid crystal composition includes a liquid crystal material exhibiting a blue phase and a liquid crystalline monomer represented by the following general formula (G1). Note that the liquid crystal composition may include a non-liquid-crystalline monomer and a polymerization initiator. In the general formula (G1), X represents a mesogenic skeleton; and Y1 and Y2 individually represent an alkylene group having a sum of carbon atoms and/or oxygen atoms of 1 to 20. Also in the general formula (G1), the alkylene group and the alkyl group may include a carbonyl group and may have an ether bond. In addition, the carbonyl group and the ether bond may form an ester structure. In the general formula (G1), Z1 and Z2 individually represent an acryloyl group or a methacryloyl group.
