Chiral agent compound, cholesteric liquid crystal composition comprising chiral agent compound and use thereof

Abstract

The present invention discloses photosensitive chiral agent compound S, a cholesteric liquid crystal composition containing the photosensitive chiral agent compound S, and the use of the cholesteric liquid crystal composition in a liquid crystal display element and a liquid crystal display. The photosensitive chiral agent compound S has the properties of high HTP value, good solubility, and short switching time. The cholesteric liquid crystal composition comprising the photosensitive chiral agent compound S has high reflectance retention ratio, which ensures RGB color uniformity and does not require complicated pixel design; low viscosity, which ensures compatibility with existing large-scale panel fabrication processes; and fast UV-induced color switching speed, which results in reduced time during the UV process and lowered production costs. The photosensitive chiral agent compound S can be widely used in optical devices such as liquid crystal electronic books and outdoor and vehicle-mounted displays.
