Moreover, the surface light source device includes a reflecting bar disposed on an emitting side of the planar light from the first and second light guide rods, and a reflecting portion taking such a box shape as to have an internal wall serving as a reflecting surface, and having an opening portion on a surface at the emitting side of the planar light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface light source device and liquid crystal display device","description":"A surface light source device includes a first light source for emitting first light, a first light guide rod for causing the first light to be incident thereon and converting the first light into fir","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739921","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.
