Abstract
An object of the present invention is to obtain a polymer-stabilized liquid crystal composition which can suppress dependency of a driving voltage on a temperature by decreasing the driving voltage. To a low-molecular liquid crystal compound, a chiral compound, and a specific acrylate and a polymerizable liquid crystal compound as polymerizable acrylate compounds are added, to prepare a polymer-stabilized liquid crystal composition. By subjecting the polymer-stabilized liquid crystal composition to ultraviolet exposure while maintaining a desired alignment state to form a polymer chain in a liquid crystal phase, a polymer-stabilized liquid crystal display device containing a low-molecular liquid crystal in a stabilized alignment state is obtained.
