US 2019/0316038 A1 · LIQUID CRYSTAL COMPOSITION AND DISPLAY USING COMPOSITION

Abstract

Provided are a polymerizable composition of a polymerizable compound represented by formula I and a polymerizable compound represented by formula II, a liquid crystal composition formed by combining this polymerizable composition with a specific liquid crystal component, particularly a PSVA liquid crystal composition suitable for display or TV applications, and a PSA-IPS liquid crystal composition for an IPS mode; in particular, the polymerizable liquid crystal composition has a good solubility, and an adjustable rate of polymerization and morphology after polymerization; furthermore, a “material system” formed from the selected polymerizable component and liquid crystal component has a low rotary viscosity and good photoelectric properties, and has a high VHR after (UV) photoradiation, this avoiding the problems of the occurrence of afterimages in final displays, etc.
