(57) [Summary] General formula (I) (X 1 : H atom, CH 3 group, r: 0, 1, 6-membered ring A, B and C: 1,4-phenylene group which can be substituted by F atom, 1, Y 1 and Y 2 such as 4-cyclohexylene group: one is —CH 2 CH 2 -, - CH 2 O - ,, - OCH 2 CH 2 CH 2 - , etc., The other is a single bond, -CH 2 CH 2 -, - CH 2 O -, - OC H 3 —, —COO—, —OCO—, —C≡C—, etc., Y 3 : Single bond, —O—, —COO—, —OCO—, Z 1 : H atom, halogen atom, CN group, C 1-20 alkyl, Alkenyl. A liquid crystal composition containing the liquid crystal (meth) acrylate compound of (1). The liquid crystal composition of the present invention is a polymerizable liquid crystal composition having a lower limit of the liquid crystal temperature at room temperature or lower, and enables photopolymerization at a temperature lower than room temperature. Therefore, it is very useful as a material for manufacturing optical elements such as an optical compensator, a polarizing beam splitter, an optical low-pass filter, and a polarizing prism having excellent transparency. |
