PROBLEM TO BE SOLVED: To provide a liquid crystalline compound having necessary general physical properties such as a low viscosity, suitable optical anisotropy, suitable dielectric anisotropy and excellent compatibility with other liquid crystalline compounds, a liquid crystal composition and a liquid crystal-displaying element. SOLUTION: This liquid crystalline compound expressed by formula (1) [wherein, R<SB>a</SB>, R<SB>b</SB>are independently each e.g. an alkyl; ring A<SP>1</SP>to A<SP>6</SP>are independently each e.g. 1,4-cyclohexylene; Z<SP>11</SP>to Z<SP>16</SP>are independently each e.g. a single bond or an alkylene; Y<SP>1</SP>, Y<SP>2</SP>are independently each e.g. H or a halogen, and Y<SP>1</SP>, Y<SP>2</SP>are not simultaneously H; (k), (l), (m), (n), (p) and (q) are independently each 0 or 1 and the sum of the (k), (l), (m), (n), (p) and (q) is 1, 2 or 3], the liquid crystal composition containing the same and the liquid crystal-displaying element containing the composition are provided.
