摘要：

The present invention provides a method for manufacturing a liquid crystal display device including a photo-alignment film and capable of sufficiently improving the display quality. The method for manufacturing a liquid crystal display device of the present invention is a method for manufacturing a liquid crystal display device including a photo-alignment film. The method for manufacturing a liquid crystal display device successively includes a step (1) of forming on a substrate a film from a photo-alignment-film material that contains a solvent, a polymer including a photo-functional group that is capable of causing at least one chemical reaction selected from the group consisting of photodimerization, photoisomerization, and photo-Fries rearrangement, and a polymer including a polyamic acid backbone and free from the photo-functional group; a step (2) of pre-heating the film to evaporate the solvent; a step (3) of irradiating the pre-heated film with polarized light; and a step (4) of main-heating the polarized-light-irradiated film. The liquid crystal display device is of an in-plane switching mode or a fringe field switching mode in each of which a pre-tilt angle is substantially 0°.
