Abstract
The invention relates to a liquid crystal display used as a display unit of an electronic apparatus and provides a liquid crystal display which can achieve high display quality. The liquid crystal display includes a pair of substrates provided opposite to each other, a liquid crystal having negative dielectric constant anisotropy sealed between the substrates, an alignment film formed on each of surfaces of the substrates facing each other for vertically aligning the liquid crystal, the film being formed using a material including an epoxy type cross linking agent at a concentration in the range from 0% by weight to 0.01% by weight inclusive, and a polymer layer for regulating the direction of alignment of the liquid crystal formed in the vicinity of an interface between the liquid crystal and the alignment film as a result of polymerization of a polymeric component included in the liquid crystal.
