Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/075508
Kind Code:
A1
Abstract:
Provided are: a liquid crystal composition in which a large amount of polymerizable monomer is dissolved, the liquid crystal composition capable of forming a pre-tilt angle in a shorter time by sufficiently increasing the rate of polymerization thereof; and a liquid crystal display which uses a related liquid crystal composition, has a sufficient pre-tilt angle , has little or no change in pre-tilt angle, and is excellent in terms of voltage holding ratio (VHR) and response performance. A liquid crystal composition according to the present invention is characterized by containing: a liquid crystal molecule; a polymerizable monomer A which has a mesogenic skeleton and at least two polymerizable groups bonded to the mesogenic skeleton, wherein all of the polymerizable groups are directly bonded to the mesogenic skeleton; and a polymerizable monomer B which has a mesogenic skeleton and at least two polymerizable groups bonded to the mesogenic skeleton, wherein all of the polymerizable groups are bonded to the mesogenic skeleton via spacer groups.
