Abstract

The invention provides a polymerized liquid crystal combination. According to the polymerized liquid crystal combination, at least one compound containing two polymerizable groups and conforming to a general formula I serves as a first component, and at least one compound containing a polymerizable group and conforming to a general formula II serves as a second component. Compared with other polymer liquid crystal compounds in the prior art, the polymerized liquid crystal combination is low in melting point and large in optical anisotropy and can be used for preparing a phase difference film and improve optical performance of a liquid crystal display.

Description

technical field [0001] The invention relates to a liquid crystal composition, especially a polymerizable liquid crystal composition. Background technique [0002] In recent years, liquid crystal compounds and liquid crystal materials have become a research hotspot. With the development of the information industry, it has been widely used in electronic display. At present, simple liquid crystal displays can no longer meet people's requirements for visibility (brighter, better contrast, higher viewing angle, etc.), and it is necessary to develop high-performance liquid crystal materials to improve display quality. However, such a demand cannot be fully satisfied by merely improving the liquid crystal cell itself, and thus largely depends on the performance improvement of optical films such as retardation films. Retardation film controls optical anisotropy through optical compensation, improves optical efficiency, improves viewing angle, and is currently an important means to...
