Patents by Inventor Shohgo Fujioka

Shohgo Fujioka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Liquid crystal display device
    Patent number: 7084943
    Abstract: The present invention provides a liquid crystal display device having a high display quality. The liquid crystal display device displays an image by applying a voltage by a first electrode and a second electrode across a liquid crystal layer which takes a vertical alignment in the absence of an applied voltage. The first electrode includes a lower conductive layer, a dielectric layer covering at least a portion of the lower conductive layer, and an upper conductive layer provided on one side of the dielectric layer which is closer to the liquid crystal layer. The upper conductive layer includes a first opening, and the lower conductive layer is provided so as to oppose at least a portion of the first opening via the dielectric layer.
    Type: Grant
    Filed: April 13, 2005
    Date of Patent: August 1, 2006
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Masumi Kubo, Akihiro Yamamoto, Takashi Ochi, Kazuhiro Maekawa, Shohgo Fujioka
