Abstract: Disclosed is a nanocapsule liquid crystal display device. The display includes a liquid crystal panel having a substrate and a nanocapsule liquid crystal layer over the substrate; a first polarizing plate on an outer surface of the substrate and including a first polarizing layer; and a second polarizing plate directly on an outer surface of the nanocapsule liquid crystal layer and including a second polarizing layer and a phase difference layer, wherein a retardation of the nanocapsule liquid crystal layer is compensated by the phase difference layer.

Abstract: A nano capsule liquid crystal layer and a liquid crystal display having the same are provided. The nano capsule liquid crystal layer includes a buffer layer and a plurality of nano capsules disposed in the buffer layer. An inside of each of the nano capsules includes liquid crystal molecules, and additives each having a center molecule and at least two first peripheral molecules connected to the center molecule and spaced apart from each other, and that are mixed with the liquid crystal molecules. The first peripheral molecules have a same phase as the liquid crystal molecule.
