  • Patent number: 8049848
    Abstract: A liquid crystal display having a wide viewing angle and easily manufactured. The liquid crystal display comprises an upper substrate and a lower substrate, and a liquid crystal material disposed between the upper substrate and the lower substrate. The liquid crystal display has a conductive protrusion disposed on the surface of the upper substrate opposing to the lower substrate. The conductive protrusion is disposed over a scanning electrode line or a signal electrode line and has the same potential as that of the upper electrode. As another structure, each of pixel electrodes on the lower substrate has a smaller area than that of a common electrode on the upper substrate and is covered by the common electrode, and each of the pixel electrodes comprises an electrode portion having approximately symmetrical shape.

  • Publication number: 20110076353
    Abstract: Provided are processes such as a photo-imprinting process having high productivity without causing defacement of an expensive mold. In the photo-imprinting process of the invention, a pattern is transferred to a resin layer 2 by forming the resin layer 2 by applying a rework type photocrosslinking/curing resin to a substrate 1, pressing a mold 3 to the resin layer 2, irradiating the resin layer 2 with light having a first wavelength, and detaching the mold 3 from the resin layer 2. The rework type photocrosslinking/curing resin crosslinks/cures by irradiation with light having the first wavelength and is solubilized in a solvent by irradiation with light having a second wavelength shorter than the first wavelength or by heating. Therefore, even if grooves of the mold 3 are obstructed with the crosslinked/cured resin, the crosslinked/cured resin can be easily removed by resolubilizing it by, for example, irradiating the mold 3 with light having the second wavelength.

  • Patent number: 7495734
    Abstract: An in-plane-switching liquid crystal display unit has a two-dimensional matrix of pixel regions each including a first auxiliary region and a second auxiliary region. When no electric field is applied, liquid crystal molecules in the first and second auxiliary regions are directed in respective orientations that lie at 90° with respect to each other. When a voltage is applied, the liquid crystal molecules are rotated in the same direction while maintaining their orientations in the first and second auxiliary regions at 90° with respect to each other. Alternatively, the liquid crystal molecules in the first and second auxiliary regions are directed in the same orientation when no electric field is applied, and when a voltage is applied, the liquid crystal molecules are rotated 15 opposite directions while maintaining their orientations in symmetric relationship.
