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 realizing excellent display characteristics by being used in a liquid-crystal display element provided with a photo-alignment film, 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 using a liquid-crystal composition containing at least one compound selected from the group consisting of compounds represented by the following General Formula (I) is provided.
