Abstract:
The present invention provides a liquid crystal display device capable of reducing the probability of image sticking. The liquid crystal display device includes a pair of substrates and a liquid crystal layer between the substrates. At least one of the substrates includes an alignment film and a polymer layer on the alignment film. The polymer layer includes monomer units derived from at least two species of polymerizable monomers. The at least two species of polymerizable monomers include at least two species of monomers selected from the group consisting of: specific polyfunctional monomers and specific monofunctional monomers.
