Abstract
A liquid crystal display device includes: a polymer layer that controls the alignment of liquid crystal molecules on at least one of the first substrate and the second substrate. The polymer layer is formed by polymerizing one or more radical-polymerizable monomers added to the liquid crystal layer. At least one of the radical-polymerizable monomers is a compound represented by P-Sp-Z-A-(Z-A)-Z-Sp-P. In an example encompassed by the formula, P represents a radical-polymerizable group. Spand Speach represent a direct bond or an alkylene group. Arepresents a divalent aromatic hydrocarbon group. Arepresents a phenylene group. Z, Z, and Zmay be the same or different. At least one of Z, Z, and Zrepresents a direct bond, or an —NRCO— group or —CONR— group. R represents a hydrogen atom or a C-Clinear alkyl group or alkenyl group. nis 0 or 1.
