A composition having a liquid crystal phase in a wide temperature range, low viscosity, good solubility at low temperatures, high specific resistance and voltage holding ratio, and stable to heat and light, and the composition By using the product, a liquid crystal display element such as an IPS type or a TN type, which has excellent display quality and hardly causes display defects such as image sticking or dripping marks, is provided with a high yield. (M-1) One or more compounds in which a biphenyl skeleton and a phenyl ring are linked by a -CF2O- bond; and (M-3) a skeleton of the compound (M-1). One or more compounds having a structure in which a pyran ring is linked, and (M-4) one or more compounds having a phenyl ring linked to the skeleton of the (M-1) compound. And a liquid crystal display device using the composition. [Selection figure] None |
