Abstract
Official abstract text for this publication.
A liquid crystal composition of the present invention has a liquid phase over a wide temperature range, low viscosity, good solubility at a low temperature, high resistivity and voltage holding ratio, and stability to heat and light, and can thus provide, in high yield, a liquid crystal display device having good display quality and causing little display defects such as image sticking, dropping marks, and the like. A liquid crystal display device using the liquid crystal composition of the present invention is useful, particularly useful for a liquid crystal display device for active matrix driving, because both fast response and suppression of display defects are achieved, and the liquid crystal display device can be applied to a liquid crystal display device for a VA mode, a PSVA mode, or a TN mode.
First claim
Opening claim text (preview).
The invention claimed is: 1. A liquid crystal composition having positive dielectric anisotropy, the composition comprising a component (A) which is a dielectrically positive component and a dielectrically neutral component (B) having a dielectric anisotropy of more than −2 and less than +2, the component (A) containing a dielectrically positive compound represented by (Formula-1) and at least one dielectrically positive compound selected from the group consisting of compounds repr…
