Abstract:
1. A method for manufacturing a liquid crystal display device comprising: a step of forming a horizontal alignment film by carrying out a photo-alignment treatment of irradiating a photo-alignment film material applied to at least one substrate of a pair of substrates with polarized light, wherein the photo-alignment treatment is carried out by exposing a plurality of regions of one substrate surface of the at least one substrate of the pair of substrates, two neighboring regions among the plurality of regions which are exposed include an overlapping portion, an irradiation amount of the polarized light applied to the overlapping portion is gradually lowered in one of the two neighboring regions in a direction toward another one of the two neighboring regions, the overlapping portion of the two neighboring regions has a width of 20 mm or wider, the liquid crystal display device has an In-Plane Switching alignment mode or a Fringe Field Switching alignment mode, and an entirety of each of the plurality of regions is exposed through one light transmission portion of a photo mask.
