WIPO Patent Application WO/2015/053505

Kind Code:

A1

Abstract:

The present invention relates to: a fluorinated phenyl-thiophene-based polymerizable mesogenic compound with improved solubility in a host liquid crystal; a preparation method therefor; and a polymerizable liquid crystal composition containing the same. The phenyl-thiophene-based polymerizable mesogenic compound of the present invention increases the solubility in a vertically aligned host liquid crystal by asymmetrically introducing a fluorine group as a solubility-improving group to a phenyl-thiophene core and introduces a methacrylate as a photoreactive group, thereby improving the stability of a pretilt angle after photo-cross-linking, and thus can be useful as a polymerizable liquid crystal composition, particularly, a polymerizable liquid crystal composition for a polymer-stabilized alignment liquid crystal display.
