General physical properties required for liquid crystalline compounds, stability to heat, light, etc., small viscosity, moderately sized refractive anisotropy values, moderately sized dielectric anisotropy values, steep electro-optic properties, nematic phase wide temperature range, and other liquid crystalline compounds A liquid crystalline compound having excellent compatibility with, particularly a liquid crystalline compound having a wide temperature range of nematic phase is provided. The compound represented by Formula (i). For example, R 1 and R 2 are alkyl having 1 to 8 carbons or alkenyl having 2 to 8 carbons; Ring A 1 is trans-1,4-cyclohexylene or 1,4-phenylene; Ring A 2 is trans-1,4-cyclohexylene or 2,3-difluoro-1,4-phenylene; Q 1 and Q 2 are fluorine or chlorine; h is 0, 1 or 2; |
