  • Publication number: 20240168327
    Abstract: A liquid crystal display device includes a first substrate, a second substrate disposed more to a viewer side than the first substrate, and a liquid crystal layer provided between the first substrate and the second substrate, with a plurality of pixels being arrayed in a matrix shape. Each pixel includes a reflective region for display in a reflection mode. The first substrate includes a thin film transistor provided corresponding to each pixel, a pixel electrode electrically connected to the thin film transistor, and a reflective layer located at least in the reflective region. The first substrate further includes a common electrode adjacent to the pixel electrode with a dielectric layer interposed between the pixel electrode and the common electrode. At least one from among the pixel electrode and the common electrode includes at least one slit.

  • Publication number: 20240168339
    Abstract: A liquid crystal display device includes a first substrate, a second substrate disposed on a viewer side relative to the first substrate, a liquid crystal layer provided between the first substrate and the second substrate, a polarizer disposed on the viewer side relative to the liquid crystal layer, and a phase difference layer disposed between the polarizer and the liquid crystal layer, and also includes a plurality of pixels arrayed in a matrix shape. The first substrate includes a reflective layer that reflects light, a first electrode and a second electrode that can generate a transverse electrical field in the liquid crystal layer, and a first horizontal alignment film in contact with the liquid crystal layer. The second substrate includes a second horizontal alignment film in contact with the liquid crystal layer. The liquid crystal layer takes a twist alignment when no voltage is applied.

  • Patent number: 11617868
    Abstract: The balloon catheter of the present invention is provided with a balloon base at a front end of a tubular catheter body having a predetermined length. The balloon base includes a cylindrical base having a larger diameter than an outer diameter of the catheter body, and a lumen having substantially the same diameter as the outer diameter of the catheter body is formed on the base over an entire length with both ends opened. A central axis of the lumen is inclined at a predetermined angle with respect to a central axis of the base concentric with a central axis of the catheter body, and an outer peripheral surface is formed in parallel with the central axis of the base. The balloon is provided on the outer peripheral surface of the parallel base to obliquely inflate with respect to the central axis of the catheter body during inflation.
