Abstract:
Defective display by a liquid crystal display device is reduced. In a liquid crystal composition which contains a liquid crystal material exhibiting a blue phase and has a transmission spectrum with a single peak in a temperature range where the liquid crystal material exhibits a blue phase, it is found that the blue phase of the liquid crystal material can be stabilized in a wide temperature range by polymer stabilization treatment. Thus, the liquid crystal composition allows the polymer stabilization treatment to be achieved in a wider temperature range. This makes it possible to reduce defective orientation in a composite of polymer and liquid crystal formed by subjecting the liquid crystal composition to the treatment. As a result, it is possible to reduce defective display by a liquid crystal display device which includes the composite of polymer and liquid crystal.
