Abstract:
1. A liquid crystal display having a liquid crystal display element, the liquid crystal display element comprising: a pair of alignment films provided on mutually facing sides of a pair of substrates; and a liquid crystal layer which is provided between the pair of alignment films and contains a liquid crystal molecule having a negative dielectric anisotropy mixed with a molecule which has a ring structure and a spacer linking the ring structure, wherein at least one of the pair of alignment films contains a cross-linked compound obtained by cross-linking a polymer compound having a cross-linkable functional group as a side chain, wherein the mixture of the liquid crystal molecule and the molecule which has the ring structure and the spacer linking the ring structure is given a pre-tilt by the cross-linked compound, wherein the pre-tilt of the liquid crystal molecule and the molecule which has the ring structure and the spacer linking the ring structure increases a response speed to a driving voltage, and wherein the liquid crystal molecule and the molecule which has the ring structure and the spacer linking the ring structure is
