Title:
LIQUID-CRYSTAL DISPLAY ELEMENT AND METHOD FOR MANUFACTURING LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/053233
Kind Code:
A1
Abstract:
A liquid-crystal display element provided with the following: a pair of substrates opposite each other; a liquid-crystal layer sandwiched between said substrates; and a liquid-crystal alignment film, obtained from a liquid-crystal alignment agent containing a polymer, on the liquid-crystal-layer side of at least one of the substrates. The liquid-crystal layer is made from a liquid-crystal composition that contains a polymerizable compound and a liquid crystal. Said polymerizable compound has a polymerizable unsaturated bonding group, a functional group that forms a hydrogen bond, and at least one aromatic ring near said functional group. The functional group forms intermolecular hydrogen bonds so as to form a mesogenic structure.
