Abstract:
The invention provides a liquid crystal display element hardly generating drop marks at the time of producing, and having high reliability and improved properties of a liquid crystal display element such as dielectric anisotropy, viscosity, a nematic phase upper limit temperature, or rotational viscosity (γ 1 ) without deteriorating the properties of the liquid crystal display element and burn-in properties of the liquid crystal display element, and a method for producing the same. In addition, according to the invention, it is possible to effectively use the liquid crystal display element as a display element of a liquid crystal TV, a monitor, and the like, due to excellent high-response speed, a low frequency of occurrence of burn-in, a low frequency of generation of drop marks at the time of the producing, excellent properties of the liquid crystal display element, and high reliability.
