The light source is disposed adjacent to the light-incident end face and in the position shifted from the center of the width of the light guide intersecting the direction in which the light source emits light. The light-incident end face of the light guide has at least one projection or recess in the direction intersecting the light-exiting direction of the light source. The projection or recess has an asymmetrical shape inclined in the direction intersecting the light-exiting direction of the light source. The projection or recess is inclined in one of directions intersecting the light-exiting direction of the light source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illumination system, liquid crystal device, and electronic device","description":"An illumination system includes: a light source that emits light; and a light guide that introduces the light through a light-incident end face facing the light source and that lets out the light from","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488080","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.
