Abstract

Provided is a liquid crystal composition which can be readily synthesized, and which has high ability to suppress crystallization. The liquid crystal composition contains at least one compound represented by the following general formula (1), at least one compound represented by the following general formula (2), and at least one compound represented by the following general formula (3).

Description

technical field [0001] The present invention relates to a liquid crystal composition useful for various applications represented by materials for various optical members such as an optically anisotropic film and a heat insulating film, a method for producing a polymer material using the liquid crystal composition, and a polymer material And films, polarizers and liquid crystal display devices. Background technique [0002] Liquid crystal materials are used in many industrial fields such as retardation plates, polarizing elements, selective reflection films, color filters, anti-reflection films, viewing angle compensation films, holograms, and alignment films. Among them, bifunctional liquid crystalline (meth)acrylate compounds have high versatility and are used in many applications. [0003] However, the crystallinity of the bifunctional liquid crystalline (meth)acrylate compound is very high, and the bifunctional liquid crystalline (meth)acrylate compound alone or in combi...
