The light modulation element has a pair of transparent substrates disposed separately and oppositely, a pair of electrodes provided on respective surfaces of the pair of transparent substrates, and a light modulation layer provided in a gap between the pair of transparent substrates. The light modulation layer includes a first region, having optical anisotropy, responsive to an electric field, and a second region, having optical anisotropy, unresponsive to an electric field. The second region has a striped structure with average striped texture size of 0.05 μm to 10 μm both inclusive in a short axis direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device and display device","description":"A lighting device includes: a light guide plate; a light source disposed on a side face of the light guide plate; and a light modulation element disposed on a surface or in the inside of the light gui","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493526","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.
