Title:
POLYMERIZABLE LIQUID-CRYSTAL COMPOSITION, LIQUID-CRYSTAL DISPLAY ELEMENT, AND PROCESS FOR PRODUCING LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/074311
Kind Code:
A1
Abstract:
[Problem] To provide: a polymerizable liquid-crystal composition that can give a liquid-crystal display element which includes a liquid-crystal layer having a high polymer-component content and which has high polymer homogeneity and greatly mitigated display unevenness; and a liquid-crystal display element obtained using the polymerizable liquid-crystal composition.
[Solution] A polymerizable liquid-crystal composition characterized by comprising a radical-polymerizable monomer ingredient (A), a liquid-crystal material (B), and a compound (C) represented by structural formula (1) as essential components.
(In structural formula (1), Ar represents a divalent aromatic hydrocarbon group, etc.; Z's each independently represent a single bond, a C1-12 linear or branched alkyl group, etc.; R1 represents a C1-8 linear or branched alkyl group, etc.; R2 represents a hydrogen atom, a C1-8 linear or branched alkyl group, etc.; and n is an integer of 0-3.)
