Abstract:
1. A liquid crystal display device comprising: a substrate; a liquid crystal layer; and a first layer disposed between the substrate and the liquid crystal layer, wherein the liquid crystal layer is disposed on the first layer and includes a liquid crystal material having a negative dielectric constant anisotropy; the first layer is formed on a second layer; the first layer controls the alignment of liquid crystal molecules included in the liquid crystal layer; the first layer has been formed by polymerization reaction of at least one kind of monomer; the polymerization reaction is initiated by radicals generated through an irradiation of the at least one kind of monomer with light; the second layer is an alignment layer for vertically aligning adjacent liquid-crystal molecules in the liquid crystal layer and includes a polymer compound having a main chain that contains an imide structure; and the main chain has an imidization ratio of 50% or more, wherein the at least one kind of monomer is a condensed aromatic compound represented by the following formula (II): wherein the P A wherein a hydrogen atom A
