| abstract |
The purpose of the present invention is: to provide a composition which has a positive Δε, and which has a liquid crystal phase with a wide temperature range, and has low viscosity, excellent low-temperature solubility, a high resistivity and voltage holding ratio, and an excellent balance of stable characteristics against heat and light; and, by using this composition, to further provide, with good yield, FFS-type, IPS-type or TN-type liquid crystal elements which have excellent display quality and which are unlikely to result in display defects such as burn-in or drip marks. This invention provides a composition which contains a compound represented by general formula (L-1) and a compound represented by general formula (i), and in which, of the compounds in which at least one of R L11 and R L12 in general formula (L-1) is an alkenyl group of 2-8 carbon atoms, the content of the compounds in which both of R L11 and R L12 in general formula (L-1) are an alkenyl group is optimized; the present invention also provides a liquid crystal display element using said composition. |
