The present invention provides a tetralin compound represented by the following formula: R-X-A1-Y1-A2-(Y2-A3)n-Z-R* wherein R is an alkyl group of 3-20 carbon atoms; X is -O-CO-, -O- or a single bond; n is 0 or 1; each of A1, A2 and A3 is a divalent aromatic group; each of Y1 and Y2 is -COO-, -O-CO-, -CH2CH2-, -CH2O- or -OCH2-; Z is -O-, -O-CO- or a single bond; and R* is a specific optically active group. The invention also provides a liquid crystal material comprising the above-mentioned tetralin compound, a liquid crystal composition comprising the tetralin compound and a liquid crystal compound other than the tetralin compound, and a liquid crystal element using the tetralin compound. The tetralin compound of the invention is favorably used as a liquid crystal material because it has a large tilt angle and shows excellent liquid crystal properties.
