The present invention provides a liquid crystal display device capable of reducing image sticking phenomena and of maintaining the voltage holding ratio, the liquid crystal display device being produced using photo-alignment technology and PSA technology in combination. The liquid crystal display device according to the present invention includes a pair of substrates, a liquid crystal layer disposed between the pair of substrates, an alignment film formed on at least one of the pair of substrates, and a polymer layer for controlling the alignment of liquid crystal molecules formed on the alignment film, wherein the polymer layer is formed by polymerization of one or more species of monomers added in the liquid crystal layer, the polymerization being initiated by radicals generated of the one or more species of monomers upon absorption of light, and the alignment film includes a polymer material having a main chain that contains an imide structure and a side chain that contains a photoreactive functional group, and has undergone a photo-alignment treatment. |
