  • Patent number: 9766654
    Abstract: There is disclosed a liquid crystal display device in which a touch panel and a front window are attached to a front surface of a liquid crystal display panel with a touch-panel flexible wiring substrate mounted to the touch panel. The front window is attached to the touch panel by an adhesive sheet. The touch panel and the front window may be peeled off in the vicinity of the portion in which the touch-panel flexible wiring substrate is mounted to the touch panel, due to mechanical shock. In order to prevent the peeling-off of the touch panel and the front window, protrusions are formed in the adhesive sheet to increase the adhesive force between the touch panel and the front window in this portion.

  • Patent number: 8891043
    Abstract: A first panel before attaching at least a polarizing plate on an upper surface thereof is prepared, in order to configure a liquid crystal display panel. A second panel having a polarizing plate at least on one surface is prepared, in order to configure a parallax barrier liquid crystal panel which enables a naked-eye stereoscopic view. An adhesive is interposed between the upper surface of the first panel and the polarizing plate of the second panel. The second panel is larger than the first panel, and the polarizing plate is larger than the first panel. The first panel and the second panel are attached to each other so that the polarizing plate protrudes from the upper surface of the first panel.

  • Patent number: 8711306
    Abstract: A liquid crystal display device includes a light transmitting substrate arranged on a parallax barrier liquid crystal panel; a light blocking frame formed on the light transmitting substrate; and a frame positioned in a state where the frame faces an end surface of a light guide plate. The light blocking frame is formed to cover a portion of the frame arranged adjacent to the light guide plate and a portion of the frame outside the portion The frame includes a body made of a material which reflects some of light incident on the body and allows some of the light to pass through the body, and a light blocking film formed on a portion of a surface of the body on a liquid-crystal-display-panel side which projects from the liquid crystal display panel while avoiding a surface of the body which faces the light guide plate.

  • Patent number: 8384850
    Abstract: The first line and the plurality of second lines are formed on the light-emitting diode substrate and on the connection substrate. The plurality of second lines are arranged, on the connection substrate, in the same direction as a direction in which the plurality of light-emitting diodes mounted on the light-emitting diode substrate are arranged. The first line is formed outside the plurality of second lines, on the connection substrate. The plurality of second lines are formed without intersecting with one another, on the light-emitting diode substrate. The first line is formed, on the light-emitting diode substrate, so that the first line extends along with a periphery of the light-emitting diode substrate from a connection part with respect to the connection substrate so as to come around to an opposite side of the connection part with respect to the connection substrate.
