Abstract

Official abstract text for this publication.

There is provided a liquid crystal display device including a liquid crystal display element including a first alignment film and a second alignment film provided on opposing surfaces of a pair of substrates, and a liquid crystal layer arranged between the first alignment film and the second alignment film and including crystal molecules having negative dielectric constant anisotropy. At least the first alignment film includes a compound in which a polymer compound having a first side chain and a second side chain is crosslinked or polymerized. The first side chain has a crosslinkable functional group or a polymerizable functional group. The second side chain has a structure inducing dielectric anisotropy. The liquid crystal molecules are pretilted by the first alignment film.
