  • Patent number: 8217920
    Abstract: A display device has a data-holding circuit with a capacitance and a display portion with a plurality of pixel electrodes, formed on a first carrier substrate. In the display device, a second carrier substrate disposed opposite the first carrier substrate is placed above the display portion, but the opposing substrate is not present above the area in which the data-holding circuit is disposed. The parasitic capacitance of the data-holding circuit can thereby be reduced. Therefore, the capacitance in the data-holding circuit can be reduced and the area required can be reduced as well. The display data of all the pixels is sent serially to the liquid crystal module without high-speed transfer for each frame time interval, and size can be reduced because the controller IC and interface circuit are formed on the same substrate as the display device substrate.

  • Patent number: 8212970
    Abstract: Disclosed is a liquid display device that is capable of suppressing a change in contrast of a liquid crystal display panel, in which a screen is a curved surface with a curvature in one direction. In a liquid crystal display panel having a cylindrical surface, an upper polarizing plate is attached to a color filter substrate. The upper polarizing plate receives tensile stress in a curved direction. Tensile stress adversely affects polarization characteristics of the upper polarizing plate. According to an embodiment of the invention, if the absorption axis A of the upper polarizing plate is adapted to match with the curved direction of the liquid crystal display panel, it is possible to prevent a change in polarization characteristics of the upper polarizing plate. As a result, it is possible to obtain an image with excellent contrast for a long term.

  • Patent number: 8111337
    Abstract: An LCD projector has LCD panels, each including polarization plates one on the light incidence side and another on the light emitting side of each LCD panel. The LCD panel is provided with a highly transparent auxiliary polarization plate between the LCD panel and the polarization plate on the light emitting side. The LCD panel is further provided with an optically anisotropic transparent substrate for supporting the highly transparent auxiliary polarization plate. The transparent substrate is arranged such that one of its anisotropic optical axes is inclined at an angle not more than 0.5 degrees with respect to the face of the auxiliary polarization plate when the face is parallel to the direction of light propagation. This arrangement ensures longer lives of the polarization plates on the light emitting sides while suppressing color irregularity on a black screen and degradation of picture contrast of the LCD projector.

  • Publication number: 20120026450
    Abstract: A method of manufacturing a liquid crystal panel according to the present invention includes the steps of providing a marking pad including a marking region formed of a stack constituted only of a metal film serving as a lower layer and an ITO film serving as an upper layer on a main surface of a glass substrate, bonding a glass substrate to the glass substrate so as to be opposed to the main surface of the marking region in the marking pad at a distance therefrom, and providing marking by providing a through hole in the marking region in the marking pad by irradiating the marking region in the marking pad with laser beams through the glass substrate. Thus, the marking pad provided on the glass substrate for the liquid crystal panel can be provided with marking of high definition even though laser beams are emitted through another glass substrate for a liquid crystal panel paired with the glass substrate for the liquid crystal panel.

  • Patent number: 8098361
    Abstract: To control the positioning of a spacer more accurately in a liquid crystal display device to prevent display defects due to incorrect positioning in a display region. To provide a liquid crystal display device with higher image quality and reliability, and to provide a method for manufacturing the liquid crystal display device with high yield. In a liquid crystal display device, a region onto which a spherical spacer is discharged is subjected to liquid-repellent treatment in order to reduce the wettability with respect to a liquid in which the spherical spacer is dispersed. The liquid (the droplet) does not spread over the liquid-repellent region and is dried while moving the spherical spacer toward the center of the liquid. Thus, incorrect positioning shortly after discharging, which has been caused by the loss of control in the liquid, can be corrected by moving the spherical spacer while drying the liquid.

  • Patent number: 8089434
    Abstract: A sheet in an electronic display is composed of a substrate containing an array of wire electrodes. The wire electrodes are preferably electrically connected to patterned transparent conductive electrode lines. The wire electrodes are used to carry the bulk of the current. The wire electrodes are capable of being extended away from the substrate and connected directly to the printed circuit board. The transparent conductive electrode (TCE) is used to spread the charge or voltage from the wire electrode across the pixel. It is a patterned film and must be at least 50% transparent, and, for most applications, is preferably over 90% transparent. In most display applications, the electroded surface of the electroded sheet has to be flattened. Use of a thin polymer substrate yields a light, flexible, rugged sheet that may be curved, bent or rolled.
