Claim Text:
1. A liquid crystal display device comprising a pair of substrates and a liquid crystal layer held between the pair of substrates, at least one of the substrates including an electrode, and the liquid crystal layer having negative dielectric anisotropy, wherein each of the pair of substrates includes a silane coupling layer on a surface of the corresponding substrate, a polymer layer configured to vertically align adjacent liquid crystal molecules is formed on a surface of the silane coupling layer, the polymer layer is formed by the polymerization of at least two monomers contained in a liquid crystal composition, and the at least two monomers contain a monofunctional monomer represented by the chemical formula (1): wherein in the formula (1), X represents an acrylate group, a methacrylate group, an ethacrylate group, a vinyl group, or an allyl group; m represents an integer of 0 to 4; a represents 0 or 1; b represents 0 or 1; and R represents an alkyl group having 1 to 20 carbon atoms, and a bifunctional monomer represented by the chemical formula (2): wherein in the formula (2), P
