Abstract

The present invention provides a method for producing a liquid crystal display device which can produce a liquid crystal display device with favorable voltage holding ratio reliability and reduced image sticking. The method is for producing a liquid crystal display device, which is a horizontal alignment-mode liquid crystal display device including a drive substrate provided with paired electrodes and a counter substrate, the method including: an application step of applying an alignment film material to the surface of each of the drive substrate and the counter substrate; a photo-alignment treatment step of irradiating the applied alignment film material with light; a post-baking step of baking the alignment film material having been subjected to the photo-alignment treatment to form an alignment film on the surface of each of the drive substrate and the counter substrate; and an additional irradiation step of irradiating the alignment films with light, the alignment film material containing a polymer with a (meth)acrylic backbone and a photo-functional group that undergoes a dimerization or cross-linking reaction by photo-irradiation, the additional irradiation step irradiating the alignment film formed on the surface of the counter substrate with an irradiation dose higher than the irradiation dose for the alignment film formed on the surface of the drive substrate.
