Accordingly, it is possible to provide a liquid crystal display device allowing an observer to perceive, through polarized sunglasses and with a high display quality, an image on a screen not only from a frontal viewpoint but also if an azimuth angle and a polar angle at which viewpoints are set are shifted from the frontal viewpoint."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device with triacetyl cellulose film at an observer side of front polarization plate","description":"A liquid crystal display device includes a liquid crystal panel (2) disposed between two linear polarization plates (1, 3) and a triacetyl cellulose film having biaxial optical anisotropy (4), the tri","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462300","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.
