The occurrence of defective orientation of a composite of a polymer and a liquid crystal is suppressed. Furthermore, the occurrence of defective display of a liquid crystal display device including the composite of a polymer and a liquid crystal is suppressed. The composite of a polymer and a liquid includes a plurality of domains with different periods of alignment, a boundary formed between the plurality of domains, and a region where the plurality of domains adjoin and bond to one another without the boundary. The composite of a polymer and a liquid crystal exhibits a blue phase.
