要約
(EN)
This invention provides a method for manufacturing a liquid-crystal display that contains a photo-alignment film and can substantially improve display quality. Said method for manufacturing a liquid-crystal display containing a photo-alignment film has the following steps, in this order: a step (1) in which a film of a photo-alignment-film material is formed on a substrate, said photo-alignment-film material containing a solvent and a polymer that has an optical functional group that can undergo at least one chemical reaction selected from the group consisting of photodimerization, photoisomerization, and optical Fries rearrangement; a step (2) in which the aforementioned film is subjected to preliminary heating that vaporizes the aforementioned solvent; a step (3) in which the film, having been subjected to preliminary heating, is exposed to polarized light; and a step (4) that includes an operation in which the film, having been exposed to polarized light, is subjected to a primary heating process at a plurality of temperatures from low to high. This liquid-crystal display is a fringe-field-switching-mode liquid-crystal display or an in-plane-switching-mode liquid-crystal display with a pretilt angle that is effectively 0°.
