Liquid crystal composition, composite of polymer and liquid crystal, and liquid crystal display device |
摘要 |
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. |

1. A composite of polymer and liquid crystal comprising:
a liquid crystal material; and a polymer, wherein the composite of polymer and liquid crystal is obtained by polymerization using a monomer, wherein the monomer comprises mesogenic skeleton and two alkyl chains, wherein an aspect of a texture in a surface region of the composite of polymer and liquid crystal is different from an aspect of a texture in an inner region of the composite of polymer and liquid crystal, wherein the composite of polymer and liquid crystal has a first transmission spectrum with a single peak in a temperature range where the liquid crystal material exhibits a blue phase, and wherein the first transmission spectrum is obtained by removing a second transmission spectrum obtained in a temperature range where the liquid crystal material contained in the composite of polymer and liquid crystal exhibits an isotropic phase. |
