  • Patent number: 11555151
    Abstract: A liquid crystal composition, a liquid crystal display element and a liquid crystal display comprising the liquid crystal composition belong to the field of liquid crystal display. The liquid crystal composition comprises a compound represented by formula I with a mass content of 1-10% as the first component, a compound represented by formula II with a mass content of 1-20% as the second component, more than two compounds represented by formula III as the third component, more than three compounds represented by formula IV as the fourth component, and one or more polymerizable compounds as the fifth component, the crystal composition has low rotational viscosity and low ?1/K33 on the basis of maintaining appropriate optical anisotropy. When applied to liquid crystal display elements or liquid crystal displays, the liquid crystal display has a fast response speed.

  • Patent number: 11078421
    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.
