[PROBLEMS] To satisfy various characteristics required for an electro-optical display element, particularly the above-mentioned liquid crystal display element, and have a low threshold voltage, a wide nematic temperature range, and a low viscosity. The present invention provides a liquid crystal composition and a liquid crystal display element using the liquid crystal composition, which have excellent high-speed response and can maintain a high retention rate up to a high temperature, or a liquid crystal composition and a liquid crystal display element (TN, STN) in which the above-mentioned disadvantages have been conventionally improved. , AM-LCD). SOLUTION: General formula (1), general formula (2) (R: Independently a C 1-15 alkyl, alkenyl, etc. ring A, ring B, ring C, ring D: 1,4-phenylene, trans-1,4-cyclohexylene, etc., Z 1 , Z 2 , Z 3 , Z 4 : single bond, CH 2 CH 2 , COO, OCO, CH 2 O or the like, n: 0,1, p: 0,1,2 , Y 1, Y 2: F atom, Cl atom, CN or the like, Q: OCH 2, OCF 2 , OCHF, single bond , C A nematic liquid crystal composition containing a compound selected from the group of compounds such as F 2 , OCF 2 and OCHF is used. |
