LIQUID CRYSTAL COMPOUND COMPRISING BENZOTHIAZOLE RING AND CF2O LIGAND, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY ELEMENT

WIPO Patent Application WO/2020/026583

A1

The present invention addresses the problem of providing: a liquid crystal compound satisfying at least one physical property from among high heat or light stability, high clearing point (or high maximum temperature), low liquid crystal phase minimum temperature, low viscosity, suitable optical anisotropy, high dielectric anisotropy, suitable elastic constant, good miscibility with other liquid crystal compounds, and the like; a liquid crystal composition containing said compound; and a liquid crystal display element containing said composition. The means by which the present invention solves the problem is a compound represented by formula (1), a liquid crystal composition containing said compound, and a liquid crystal display element containing said composition. In formula (1), R1 is hydrogen, an alkyl, or the like; rings A1, A2, and A3 are independently a 1,4-phenylene, a ring represented by formula (A0), or the like, with at least one ring being a ring represented by formula (A0); Z1, Z2, and Z3 are independently a single bond, -C≡C-, or the like; L1, L2, and L3 are independently hydrogen, fluorine, or the like; and a and b are independently 0, 1, 2, or 3, the sum of a and b being 0, 1, 2, or 3.
