Title:
LIQUID CRYSTAL ELEMENT AND PRODUCTION METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/143017
Kind Code:
A1
Abstract:
This liquid crystal element is provided with: a pair of substrates that are disposed to face each other; electrodes that are disposed on the opposed surfaces of the pair of substrates; a liquid crystal layer which is interposed between the pair of substrates and which is formed by curing a liquid crystal composition comprising liquid crystal and a polymerizable compound; and a liquid crystal alignment film that is formed on the surfaces on which the electrodes are disposed. The polymerizable compound contains a monofunctional (meth)acrylate compound, a polyfunctional (meth)acrylate compound, and the like. The liquid crystal alignment film is formed using a liquid crystal aligning agent containing a polymer component. The liquid crystal aligning agent contains at least one type of compound which is selected from the group consisting of silane compounds and polysiloxanes and in which the content ratio of a structural unit derived from a monomer having a specific side-chain structure is 10 mol% or less with respect to the total amount of all structural units of the polymer component.
