Abstract
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 range, and having a suitable optical anisotropy and an excellent compatibility with other liquid crystal compounds. Particularly, a liquid crystal compound having a large dielectric anisotropy is described. The compound is represented by formula (1): In the formula, for example, Ris alkyl having 1 to 20 carbons; ring A, ring A, ring A, ring A, ring Aand ring Aare independently 1,4-cyclohexylene or 1,4-phenylene; Z, Z, Z, Z, Z, Zand Zare independently a single bond, —(CH)—, —COO—, —OCO—, —CFO—, —OCF— or —CH═CH—; Xis fluorine, —CFor —OCF; and Yand Yare independently hydrogen or fluorine.
