An interface between the layers has a concave-and-convex shape, and each of a concavity and a convexity in the shape has a flat portion extending in a surface direction of the layers. A side surface of the concave-and-convex shape, which extends between the flat portions of the concavity and convexity, is a curved surface or a folded surface that is convex to the low refractive-index layer. A difference between a maximum angle and a minimum angle, which are defined between the side surface of the concave-and-convex shape and a normal direction of the layers, is not less than 3 degrees and not more than 60 degrees."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical structure comprising a concave-and-convex-shaped interface having a flat portion between a high refractive-index layer and a low refractive-index layer and display device","description":"An optical structure includes a high refractive-index layer and a low refractive-index layer laminated on the high refractive-index layer and having a refractive index lower than that of the high refr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11513391","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.
