PROBLEM TO BE SOLVED: To provide high stability to heat, light, etc., high clearing point, low minimum temperature of liquid crystal phase, small viscosity, appropriate optical anisotropy, large dielectric anisotropy, appropriate elastic constant, other liquid crystal properties A liquid crystal compound satisfying at least one of physical properties such as excellent compatibility with a compound, a liquid crystal composition containing the compound, and a liquid crystal display device including the composition are provided. A compound represented by formula (1). For example, Ra and Rb are alkyl having 1 to 10 carbons, alkenyl having 2 to 10 carbons, or alkoxy having 1 to 9 carbons; A 1 , A 2 , and A 3 are 1,4-cyclohex Is silylene or 1,4-phenylene; Z 1 and Z 2 are a single bond, — (CH 2 ) 2 —, —COO—, —CF 2 O—, or —CH 2 O—; Y 1 is a -CF 2 H or -CF 3, Y 2 is an fluorine; a, b, and d are 0, 1, 2, or a 3, c is 1 or 3.
