A novel tolan compound of the formula (I): STR1 wherein A is C1-10 alkyl, C1-10 alkoxy, cyclohexyl substituted by C1-10 alkyl at 4 position, cyclohexyl substituted by C1-10 alkoxy group at 4 position or a group of the formula: STR2 wherein Y is hydrogen or halogen and Z is C1-10 alkyl or halogen; B is a single bond or --CO--O-- or --O--CO--; D is hydrogen, C1-10 alkyl, cyclohexyl substituted by C1-10 alkyl at 4 position; and Z represents a hydrogen atom or a halogen atom. The tolan compound can increase the N-I point, decrease the viscosity, and increase the double refractive index of a liquid crystal composition without affecting the viscosity and threshold voltage Vth, and is mutually soluble with various other liquid crystal compounds, so that the compound can be used as a constituent of a liquid crystal composition in combination with these other liquid crystal materials to improve the properties of the composition.
