Particularly, a liquid crystal compound having a large dielectric anisotropy is described. The compound is represented by formula (1):In the formula, for example, R1 is alkyl having 1 to 20 carbons; ring A1, ring A2, ring A3, ring A4, ring A5 and ring A6 are independently 1,4-cyclohexylene or 1,4-phenylene; Z1, Z2, Z3, Z4, Z5, Z6 and Z7 are independently a single bond, —(CH2)2—, —COO—, —OCO—, —CF2O—, —OCF2— or —CH═CH—; X1 is fluorine, —CF3 or —OCF3; and Y1 and Y2 are independently hydrogen or fluorine."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Orthoester derivative, liquid crystal composition and liquid crystal display device","description":"A liquid crystal compound is described, having a large dielectric anisotropy, a high voltage holding ratio and stability to heat, light and so forth, maintaining a nematic phase in a wide temperature ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9605207","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.
