Abstract
The present invention addresses the problem of providing a liquid crystal display element that uses a p-type liquid crystal composition, that has excellent liquid crystal display element characteristics such as dielectric anisotropy ([delta][epsilon]), viscosity (eta), nematic phase-isotropic liquid transfer temperature (TNI), nematic phase stability at low temperatures, and rotational viscosity (gamma1), and that makes it possible to obtain excellent display characteristics as the result of the use of a horizontally aligned liquid crystal display element provided with a photoalignment film. Provided is a liquid crystal display element that has excellent stability at low temperatures and that maintains the high-speed response properties of the liquid crystal composition thereof as a resultof containing one or more compounds represented by formula (P), one or more compounds represented by formula (ii), one or more compounds represented by formula (iii), and one or more compounds represented by formula (iv).
Description
technical field [0001] The present invention relates to a liquid crystal display element using a nematic liquid crystal composition having a useful dielectric constant anisotropy (Δε) showing a positive value as a liquid crystal display material. Background technique [0002] At present, as a liquid crystal display for smartphones, a horizontal orientation method with high quality and excellent visual characteristics, such as IPS (In-Plane Switching) mode or a type of liquid crystal display element of this IPS, that is, a boundary electric field switching mode liquid crystal is widely used. Display element (Fringe Field Switching mode Liquid Crystal Display, FFS mode liquid crystal display device) (see Patent Document 1, Patent Document 2). The FFS mode is introduced to improve the low aperture ratio and transmittance of the IPS mode. Currently, as a liquid crystal composition used in a lateral alignment type liquid crystal display device, a material utilizing a p-type liqu...
