Patents by Inventor Souta Nemoto

Souta Nemoto 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).

  • Patent number: 7027115
    Abstract: A liquid crystal display device includes a first transparent substrate having a plurality of electrodes, a second transparent substrate, a liquid crystal interposed between the first transparent substrate and the second transparent substrate, an illumination light source disposed on a back side of the first transparent substrate, pixel regions arranged in a matrix, and a reflecting film formed between the first transparent substrate and the electrodes. The reflecting film has at least one light transmission aperture in each pixel region and without slits at positions corresponding to gaps between adjacent ones of the pixel regions.
    Type: Grant
    Filed: February 18, 2004
    Date of Patent: April 11, 2006
    Assignees: Hitachi, Ltd., Hitachi Device Engineering Co., Ltd.
    Inventors: Souta Nemoto, Kazutoshi Yoshida, Masao Uehara, Noboru Hoshino, Yoshiaki Nakamura, Masayoshi Fujieda, Koji Hiraga

  • Patent number: 6697137
    Abstract: A liquid crystal is interposed between a first transparent substrate having first electrodes and a second transparent substrate having other electrodes. Pixel regions are formed at portions where the first electrodes and the other electrodes are opposed to each other. A semitransparent reflecting film is formed between the first transparent substrate and the first electrodes. The semitransparent reflecting film is formed with light transmission apertures in each pixel region. The semitransparent reflecting film also occupies portions corresponding to the gaps between the adjacent pixel regions. Alternatively, in addition to the light transmission apertures, the semitransparent reflecting film is formed with slits at positions corresponding to the gaps between the adjacent pixel regions. A light absorption film is formed between the first transparent substrate and the semitransparent reflecting film at positions corresponding to the slits, or the slits are charged with a light absorption film.
