A surface light source apparatus according to the present invention includes: a light source; a holding substrate having a main surface on which the light source is held; a light-distribution control element disposed on the main surface of the holding substrate to cover the light source, the light-distribution control element changing distribution of light emitted from the light source; and a diffuser that diffuses light emitted from the light-distribution control element. The light-distribution control element includes a diffusion part disposed at an installation surface that can abut the main surface of the holding substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface light source apparatus comprising a light-distribution control element having a diffusion part and liquid crystal display having the same","description":"Provided is a surface light source apparatus that improves homogeneity of surface illumination light, using both light rays passing through a light emitting surface of a light-distribution control ele","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10473977","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.
