(57) Abstract: A novel liquid crystal compound having a large dielectric anisotropy value, a small change in threshold voltage with temperature, and improved solubility in other liquid crystal materials at low temperatures. And to provide a liquid crystal composition containing the same. SOLUTION: General formula (1) (In the formula, R represents H or an alkyl group having 1 to 10 carbon atoms, l represents an integer of 1 to 9, m, n and o independently represent 0 or 1, and A 1 , A 2 and A 3 are independently of each other a trans-1,4-cyclohexylene group, 1,4-phenylene group in which one or more hydrogen atoms on the ring may be substituted with F, etc. are shown, and Z 1 , Z 2 and Z 3 independently represent -COO-, etc., At least one of them represents a -COO-, X represents a CF 3 or the like, Y 1 and Y 2 denotes H or F independently of one another. ) Liquid crystal compounds and the like. |
