Abstract
The present invention relates to a liquid crystal composition used in a liquid crystal display device. A problem to be solved by the invention is to provide a liquid crystal composition and a liquid crystal display device using the liquid crystal composition, the liquid crystal composition being suitable for a liquid crystal display device, causing little dropping marks during manufacture and realizing stable discharge of a liquid crystal material in an ODF process without degrading characteristics as a liquid crystal display device, such as dielectric anisotropy, bulk viscosity, nematic phase upper limit temperature, rotational viscosity γ, voltage holding ratio, etc. and image sticking characteristic of a display device. The present invention relates to a liquid crystal composition having negative dielectric anisotropy and containing compounds represented by formula (i) and formula (XIII-1-2) or formula (XIII-1-4) and also relates to a liquid crystal display device using the liquid crystal composition.
