(57) [Summary] [Object] To provide a novel liquid crystal compound exhibiting a liquid crystal phase and having a low viscosity, and a liquid crystal composition containing at least one thereof. [Structure] The following general formula (I): [In the formula, R 1 represents an optionally substituted alkyl group having 1 to 14 carbon atoms, R 2 represents a hydrogen atom or a halogen atom, and R 3 represents a hydrogen atom or an electron-withdrawing group. X and Y are the same or different and optionally substituted aromatic or non-aromatic carbon homocycle or heterocycle, m and n are 1 or 2, respectively, and Q 1 is a single bond. , An ether bond or an ester bond, Q 2 is a single bond, an ester bond, or -CH = CH -, - CH 2 CH 2 -, or an methyleneoxy bonds. ] A trifluoromethyl-substituted vinyl compound represented by the following and a liquid crystal composition showing the same. |
