The method for manufacturing a liquid crystal display device of the present invention includes 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 exposure to a plurality of regions of one substrate surface; two neighboring regions among the plurality of regions to be exposed include an overlapped part; an irradiation amount of the polarized light to the overlapped part is gradually lowered in one of the two neighboring regions toward the other of the two neighboring regions; and the overlapped part of the two neighboring regions has a width of 20 mm or wider."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing liquid crystal display device","description":"The present invention provides a method for manufacturing a liquid crystal display device, which hardly causes display unevenness in joining parts in which mutually neighboring exposure regions are ov","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9690141","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
