The polarized light irradiation device is used in alignment treatment of a photo alignment film provided on a substrate, the device including: a stage including a placement surface on which the substrate is placed; and a polarized light irradiation unit configured to irradiate the placement surface with polarized light through a polarizer in a direction tilted relative to the normal of the placement surface, wherein a polarization azimuth angle α, which is an angle of the polarization axis of the polarizer when the polarization axis of the polarizer is projected onto the placement surface, satisfies 30°<α<45°, 45°<α<60°, −60°<α<−45°, or −45°<α<−30°, as viewed in an irradiation axis direction of the polarized light with the longitudinal direction of the substrate taken to be 0°."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polarized-light irradiation device and method for manufacturing liquid crystal display device","description":"The present invention provides a polarized light irradiation device capable of setting an alignment azimuth angle θ of liquid crystal molecules to be a desired angle even when the incident angle of po","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11269220","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.
