Patent ID: 10108052

Abstract:
An object of the present invention is to provide a liquid-crystal display element using a liquid-crystal composition having negative dielectric anisotropy, capable of realising excellent display characteristics by being used in an FFS mode liquid-crystal display element, without deteriorating various characteristics as a liquid-crystal display element such as dielectric anisotropy, viscosity, a nematic phase upper limit temperature, nematic phase stability at low temperatures, and γ1, and burn-in characteristics of a display element. A liquid-crystal display element containing at least one compound selected from the group consisting of compounds by the following General Formula (I) is provided: wherein each of R1 and R2 independently represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 2 to 8 carbon atoms, A represents a 1,4-phenylene group or a trans-1,4-cyclohexylene group, k represents 1 or 2, and in a case where k is 2, two A's may be the same as or different from each other.
