Abstract
A liquid crystal display device including a liquid crystal display device that includes a first alignment film and a second alignment film that are provided on opposing face sides of a pair of substrates and a liquid crystal layer provided between the first alignment film and the second alignment film and that includes liquid crystal molecules with negative dielectric constant anisotropy, wherein the first alignment film includes a compound in which a first polymer compound that includes a cross-linked functional group or a polymerized functional group as a side chain is cross-linked or polymerized, the second alignment film includes a compound in which a second polymer compound is cross-linked or polymerized, and a pretilt is conferred on the liquid crystal molecules by cross-linking or polymerizing the first polymer compound by the first alignment film and vertically aligning the liquid crystal molecules by the second alignment film.
