Title Liquid crystal display device
Abstract To provide a liquid crystal display device that does not need any surface aligning treatment, realizes striking increase of a response speed of movie display and is free from any light leakage (produce dark field) at black display. A liquid crystal display device is composed of a pair of transparent substrates and, interposed therebetween, a polymer stabilized blue-phase liquid crystal. The liquid crystal display device utilizing the polymer stabilized blue-phase liquid crystal exhibits a large birefringence change upon application of an electric field to cell substrate in an in-plane direction. The polymer stabilized blue-phase liquid crystal is composed of a low-molecular liquid crystal capable of developing a blue phase between cholesteric phase and isotropic phase and a polymer network formed in the low-molecular liquid crystal. Further, by optimizing the type and amount of chiral dopant added to the liquid crystal, there can be provided a liquid crystal display device that is free from any light leakage (produce dark field) at black display.
