The present invention also provides a manufacturing method of the optical film including curing a polymerizable liquid crystal composition including a liquid crystal compound and a chiral agent interposed between a support and another support. In the optical film according to the present invention, an absolute value of oblique retardation is smaller. In the liquid crystal display device including the optical film, front surface brightness is high and an oblique change in the shade is suppressed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical film, liquid crystal display device, and manufacturing method of optical film","description":"The present invention provides an optical film including a light reflection layer, in which the light reflection layer is a layer in which alignment of liquid crystal molecules is immobilized, the liq","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10495791","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.
