Abstract
The present invention provides a liquid crystal display device in which image sticking seldom occurs. The liquid crystal display device according to the present invention includes a pair of substrates, and a liquid crystal layer disposed between the pair of substrates, wherein the liquid crystal layer includes a liquid crystal material having a negative dielectric constant anisotropy, at least one of the pair of substrates is provided with an alignment film for vertically aligning adjacent liquid crystal molecules, and a polymer layer formed on the alignment film for controlling the alignment of the adjacent liquid crystal molecules, and the polymer layer is formed by polymerization of at least one monomer, the polymerization being initiated by radicals generated of the monomer upon absorption of light.
