Liquid crystal display Side-chain type ferroelectric polymer liquid crystal for liquid crystal alignment film

摘要

The side chain type ferroelectric liquid crystal liquid crystal represented by the following structural formula (I) has excellent adhesion to substrates and is excellent in resistance to heat, humidity and chemical resistance and has good liquid crystal alignment properties, thereby improving the properties as a liquid crystal display device The liquid crystal display device manufactured by using the twisted nematic type super twisted nematic liquid crystal display device as well as the surface stabilized ferroelectric liquid crystal device which is difficult to uniformly control the alignment can be manufactured by using a liquid crystal alignment film having a pinhole, And has a high memory effect and a high contrast ratio as well as a high pretilt angle.;Wherein R ¹ is an alkyloxy group, R ² is an aliphatic or aromatic bicyclic ring, and R ³ is an alkoxy group and p is an integer of 10 to 150.
