Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/116555
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a liquid crystal composition which contains a polymerizable compound and which is used for producing a PSA type or PSVA type liquid crystal display element, wherein the speed of polymerization of the polymerizable compound is sufficiently rapid, and an element obtained using the composition has no, or very few, display defects caused by changes in pretilt angle, has a satisfactory pretilt angle and exhibits excellent response performance; and a liquid crystal display element obtained using the liquid crystal composition. Provided are: a liquid crystal composition that contains one or more polymerizable compounds represented by general formula (I-Np); and a liquid crystal display element obtained using these.
