The light diffusion sections have a light emitting end surface on the substrate side and a light incident end surface having an area greater than an area of the light emitting end surface on a side opposite to the substrate side. A height from the light incident end surface to the light emitting end surface of each of the light diffusion sections is greater than a thickness of the light shielding layer. The light scattering bodies are disposed further on a light emitting side than the light diffusion sections."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light diffusion member, method for producing same, and display device","description":"A light diffusion member includes a light transmissive substrate, a plurality of light diffusion sections formed on one surface of the substrate, a light shielding layer formed in a region other than ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9638840","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.
