Each of the protrusions may include n sub-protrusions (n is an integer of 2 or greater), which are stacked in a thickness direction of the base portion. Each of the n sub-protrusions may have a quadrilateral shape. A side surface of the protrusion defined by the n sub-protrusions may include at least one step portion. The optical film improves display quality of a display device in front and lateral directions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical film and display device including the same","description":"An optical film may include a first pattern layer having a first refractive index and including a base portion and a plurality of protrusions on the base portion x, and a second pattern layer disposed","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11281042","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.
