  • Patent number: 9001284
    Abstract: A liquid crystal display includes a gate line formed on an insulation substrate. A data line, insulated from the gate line, crosses the gate line. A first pixel is connected to the gate line and the data line. The pixel includes a thin film transistor having a control terminal connected to the gate line and an input terminal connected to the data line. A first liquid crystal capacitor has one end connected to an output terminal of the thin film transistor. A second liquid crystal capacitor has one end connected to the other end of the first liquid crystal capacitor. The first liquid crystal capacitor includes a first liquid crystal layer formed in a first microcavity and the second liquid crystal capacitor includes a second liquid crystal layer formed in a second microcavity.

  • Publication number: 20140184974
    Abstract: A display device is provided. The display device includes a substrate including a pixel region, a thin film transistor formed on the substrate, a light blocking member formed at a boundary of the pixel region, and a pixel electrode formed in the pixel region, the pixel electrode connected to the thin film transistor. The display device also includes a common electrode formed on the light blocking member, the common electrode spaced apart from the pixel electrode with a microcavity interposed between the common electrode and the pixel electrode, and a roof layer comprising a color filter formed on the common electrode. The display device further includes an opening formed in the common electrode and the roof layer to expose a portion of the microcavity, a liquid crystal filling the microcavity, and an overcoat formed on the roof layer to cover the opening and seal the microcavity for each pixel region.

  • Patent number: 8658399
    Abstract: Disclosed herein is a novel gluconacetobacter strain having cellulose producing activity. Specifically, the present invention relates to a novel gluconacetobacter strain producing nano-structured cellulose in a highly efficient manner. The cellulose produced by the strain, due to its superb thermodynamic properties, can be characterized as nano-structured bacterial cellulose and therefore utilized as a bio-nano-fiber. Particularly, the cellulose can be impregnated with a resin to form a cellulose-based resin which can be effectively adapted for a substrate for a liquid crystal display (LCD).
