A liquid crystal layer corresponding to the light reflective portion exhibits a retardation which is less than one-half of a retardation of the half-wavelength plate. The first quarter-wavelength plate has a slow axis which intersects a liquid-crystal molecular orientation axis at a time of no electric field application. The expression nx1>nz1>ny1 is satisfied, where nx1, ny1 and nz1 are the refractive indices at each orientation of the half-wavelength plate, and the expression nx2>nz2=ny2 is satisfied, where nx2, ny2 and nz2 are the refractive indices at each orientation of the first quarter-wavelength plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device","description":"A liquid crystal display device includes a liquid crystal display panel including a light reflective portion, a first polarizing plate located on a display surface-facing side, a half-wavelength plate","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11275272","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.
