  • Patent number: 8233125
    Abstract: A liquid crystal display having electrodes on a single substrate. A transparent planar electrode elongated in the transverse direction is formed on the inner surface of a substrate, and an insulating film is deposited thereon. A plurality of linear electrodes, which are elongated in the longitudinal direction and either transparent or opaque, are formed on the insulating film. Potential difference between the planar and the linear electrodes generated by applying voltages to the electrodes yields an electric field. The electric field is symmetrical with respect to the longitudinal central line of the linear electrodes, and has parabolic or semi-elliptical lines of force having a center on a boundary line between the planar and the linear electrodes. The line of force on the planar and the linear electrodes and on the boundary line between the planar and the linear electrodes has the vertical and the horizontal components, and the liquid crystal molecules are re-arranged to have a twist angle and a tilt angle.

  • Patent number: 7280176
    Abstract: A liquid crystal display having electrodes on a single substrate includes a transparent planar electrode elongated in the transverse direction formed on the inner surface of the substrate, and an insulating film is deposited thereon. A plurality of linear electrodes, which are elongated in the longitudinal direction and either transparent or opaque, are formed on the insulating film. When voltages applied, the electric field is symmetrical with respect to the longitudinal central line of the linear electrodes and the longitudinal central line of a region between the linear electrodes, and has parabolic or semi-elliptical lines of force having a center on a boundary line between the planar and the linear electrodes.

  • Patent number: 6256076
    Abstract: The liquid crystal display also includes pixels which is arranged in a matrix shape and have a liquid crystal capacitor and a switching element. A plurality of storage capacitors has two terminals connected to the switching elements of at least two adjacent pixels. Each pixel except the pixels located at one end of the matrix has at least two storage capacitors, while the pixels located at the end of the matrix have only one respective storage capacitor. Each pixel placed at the other end of the matrix has a storage capacitor having a terminal which is floating or connected to the previous gate line. The pixels located at the ends of the matrix are not used for display.
