Abstract

A liquid crystal display device with few drop marks left during manufacture is provided without degrading the image-sticking characteristics of the liquid crystal display device or other characteristics fundamental to liquid crystal display devices, such as dielectric anisotropy, viscosity, upper nematic phase temperature limit, and rotational viscosity (γ), and a method for manufacturing such a liquid crystal display device is also provided. A liquid crystal display deviceaccording to the present invention includes a first substrate, a second substrate, a liquid crystal composition layerdisposed therebetween, and vertical alignment layersandcontaining a polymer of a monofunctional reactive-group-containing polymerizable compound and a polyfunctional reactive-group-containing polymerizable compound.
