A refractive index of the second areas in the first direction is higher than a refractive index of the first areas in the first direction. Therefore, the optical film including first areas and second areas having different refractive indices is disposed on a polarizing film to thereby form a viewing angle adjusting film, so that diffusion and collection of light can be easily achieved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Viewing angle adjusting film and display device including the same","description":"A viewing angle adjusting film includes a polarizing film having a transmission axis in a first direction and an optical film disposed on the polarizing film and including first areas having isotropy ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11487054","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.
