Title:
COMPOUNDS HAVING DIBENZOTHIOPHENE RING, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/107394
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a liquid crystal compound that satisfies at least one physical property including a low minimum temperature for the liquid crystal phase, a low viscosity, a suitable optical anisotropy, a large negative dielectric constant anisotropy, and an excellent compatibility with other liquid crystal compounds at room temperature and low temperatures; a liquid crystal composition containing this compound; and a liquid crystal display element containing this composition. The problem is addressed by, for example, a compound represented by formula (1). Herein, for example, R1 and R2 are hydrogen, alkyl having 1 to 10 carbons, or alkoxy having 2 to 9 carbons; rings A1 and A2 are cycloalkylene having 3 to 5 carbons; Y1 and Y2 are, e.g., hydrogen or fluorine; Z1, Z2, Z3, and Z4 are, e.g., a single bond or alkylene having 1 to 6 carbons; rings N1 and N2 are, e.g., 1,4-cyclohexylene or 1,4-phenylene; a and d are 0 or 1 and 1 ≤ a + d ≤ 2; and b and c are 0, 1, or 2.
