Patents by Inventor Shuichi KIRA

Shuichi KIRA 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: 10216031
    Abstract: A technique disclosed in the specification relates to preventing a reduction in aperture ratio and visible lines between bright and dark portions. A liquid crystal display in a technique disclosed in the specification includes a plurality of pixel arranged in a liquid crystal display panel in a plan view, a light blocking layer disposed between the plurality of pixels in a plan view, and a colorant layer provided to overlap each of the plurality of pixels. The light blocking layer includes a first region and a second region narrower than the first region in a plan view. The colorant layer has a transmittance lower in a region adjacent to the second region than a transmittance in a region adjacent to the first region.

  • Patent number: 9900588
    Abstract: A display panel includes sub-pixel pairs arranged laterally at a predetermined pitch, the sub-pixel pair including two sub pixels displaying images for right and left eyes respectively. A parallax-barrier shutter panel includes sub apertures switching light-transmitting and light-blocking states by driving a liquid crystal layer held between two transparent substrates with transparent electrodes extending vertically. The sub apertures are arranged laterally at a pitch obtained by dividing a reference parallax-barrier pitch by N (N being an even number equal to or greater than four), the reference parallax-barrier pitch being determined on the basis of a predetermined design observation distance and the pitch of the sub-pixel pairs. The parallax-barrier shutter panel includes common driving areas obtained by dividing a display area laterally.
