  • Patent number: 9019446
    Abstract: A method for manufacturing a liquid crystal display device including first, second, and third pixels for displaying different colors comprises the steps of: forming a first electrode on a substrate; forming a liquid crystal layer including a cholesteric liquid crystal as a mixed material of a non-polymeric liquid crystal compound and a photosensitive chiral additive; irradiating a different intensity of light on the liquid crystal layer positioned on the first pixel, the liquid crystal layer positioned on the second pixel, and the liquid crystal layer positioned on the third pixel; and forming a second electrode facing the first electrode.
    Type: Grant

  • Patent number: 8641923
    Abstract: Disclosed is a liquid crystal mixture that includes an isotropic mixture of liquid crystal molecules and a photo-polymerizable monomer. In addition, disclosed are a liquid crystal display (LCD) including a first display panel and a second display panel facing each other, and a liquid crystal layer disposed between the first display panel and the second display panel and including a plurality of liquid crystal regions and a plurality of polymer structures positioned among the plurality of liquid crystal regions, and a method of manufacturing the liquid crystal display (LCD). The liquid crystal layer is formed of a liquid crystal mixture in which liquid crystal molecules and a photo-polymerizable monomer exist isotropically.

  • Patent number: 8089592
    Abstract: Disclosed is a full color liquid crystal display, including a lower substrate and an upper substrate facing each other, partition spacers uniformly arranged between the lower substrate and the upper substrate to form a plurality of spaces while maintaining a cell gap between the lower substrate and the upper substrate, a lower transparent electrode and an upper transparent electrode respectively provided to the lower substrate and the upper substrate in the spaces defined by the partition spacers so as to face each other, subpixels having liquid crystals which are able to reflect or absorb respective specific light wavelengths and which are separately received in the spaces defined by the partition spacers, a plurality of such subpixels constituting a single pixel to exhibit full color.
