料開発が望まれている。However, at present, there is no material satisfying all of these characteristics with a single material, and a plurality of liquid crystal and non-liquid crystal materials are mixed to satisfy the required performance as a liquid crystal composition. Therefore, it is desired to develop a liquid crystal or non-liquid crystal material excellent in one or two or more of all characteristics.

う傾向がある。In the field of display devices using liquid crystals, it is desired to improve their performance, and low voltage driving, high definition display, high contrast ratio, wide viewing angle characteristics, low temperature response characteristics, wide operation are required. A temperature range or the like is desired, and any one of these tends to be sacrificed when the other is improved.

It is desired to improve the response speed.

ち、高精細駆動が可能になる。To solve this problem, some improvement methods can be considered. One of them is to adopt a low viscosity liquid crystal composition. That is, when the viscosity of the liquid crystal composition is reduced, the response speed is improved, and it is possible to display at a practical speed even at a low temperature. Further, if the response speed is the same as that of the conventional one, it is possible to drive with a lower voltage or drive with a higher duty, that is, high-definition drive becomes possible.
