Abstract:
1. A liquid crystal display device comprising a pair of substrates, and a liquid crystal layer disposed between the pair of substrates, wherein the liquid crystal layer includes a liquid crystal material having a negative dielectric constant anisotropy, at least one of the pair of substrates is provided with an alignment film for vertically aligning adjacent liquid crystal molecules, and a polymer layer formed on the alignment film for controlling the alignment of the adjacent liquid crystal molecules, the polymer layer is formed by polymerization of at least one monomer, the polymerization being initiated by radicals generated of the monomer upon absorption of light, the alignment film includes a polymer compound having a main chain that contains an imide structure, and the main chain has an imidization ratio of less than 50%, the at least one monomer being a condensed aromatic compound represented by the following formula (II): wherein P A wherein a hydrogen atom in A
