Abstract

To provide a liquid crystal compound having high stability to heat, light and so forth, a high clearing point, a low minimum temperature of a liquid crystal phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, a suitable elastic constant and excellent compatibility with other liquid crystal compounds, a liquid crystal composition containing the compound, and a liquid crystal display device including the composition. The compound is represented by formula (1-1): wherein, for example, R 1 is hydrogen, halogen or alkyl having 1 to 20 carbons; ring A 1 , ring A 2 , ring A 3 , ring A 4 and ring A 5 are independently 1, 4-cyclohexylene or 1, 4-phenylene; Z 1 , Z 2 , Z 3 and Z 4 are independently a single bond, -(CH 2 ) 2 -, -CH=CH- or -CF=CF-: and a, b, c and d are independently 0 or 1, and a sum of a, b, c and d is one or more.
