  • Patent number: 10162206
    Abstract: Provided herewith is a liquid crystal display device comprising a substrate; first and second electrodes on a first surface of the substrate, the first and second electrodes being spaced apart from each other; a liquid crystal capsule layer on the first and second electrodes; and a dielectric layer on the liquid crystal capsule layer. In this liquid crystal display device the dielectric constant of the dielectric layer is lower than the dielectric constant of the liquid crystal capsule layer.

  • Patent number: 10061149
    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.
