Abstract
To provide a liquid crystal compound having general physical properties required for the compound, namely, a high stability to heat, light and so forth, a small viscosity, a refractive index anisotropy value having a suitable magnitude, a dielectric constant anisotropy value having a suitable magnitude and steep electro-optical characteristics, a wide temperature range of a nematic phase, and an excellent compatibility with other liquid crystal compounds, in particular, a liquid crystal compound having a wide temperature range of the nematic phase; the compound is represented by formula (1): wherein R is alkenyl having 2 to 20 carbons; ring Aand ring Aare independently 1,4-cyclohexylene, or 1,4-phenylene in which at least one of hydrogen may be replaced by fluorine; Zand Zare independently a single bond, —CHCH—, —CH═CH—, —CHO— or —OCH—; and n is 0 or 1.
