  • Patent number: 8289466
    Abstract: In a manufacturing method for a liquid crystal display device, a translucent first adhesive is placed between a first surface of a substrate and a display surface of a liquid crystal panel so that the first adhesive covers the entire surface of the liquid crystal panel. The first adhesive is cured to bond the substrate and the liquid crystal panel. The bonded substrate and liquid crystal panel are positionally aligned relative to a backlight unit. A second adhesive is placed between the substrate and the backlight unit so that the second adhesive surrounds an outer peripheral end portion of the liquid crystal panel. The first adhesive is cured to integrally bond the substrate, liquid crystal panel, and backlight unit to each other.

  • Patent number: 8026996
    Abstract: A display device includes a display panel having first and second opposing glass substrates forming a display surface, a transparent member, a first adhesive material bonding the transparent member to the entire display surface of the display panel, and a plate-like member disposed on a rear side of and supporting the display panel. A second adhesive material different from the first adhesive material is disposed between a rear surface of the transparent member and a front surface of the plate-like member so as to fixedly bond the transparent member and the plate-like member to one another.

  • Publication number: 20090185101
    Abstract: Provided are a liquid crystal display device and a manufacturing method for the liquid crystal display device, in which the liquid crystal display device is assembled to a cabinet of a portable apparatus with high accuracy, and strength of the liquid crystal display device against external force is enhanced. A manufacturing method for a liquid crystal display device (9), in which a liquid crystal panel (3) is fixed between a translucent front substrate (1) and a backlight unit (4), includes: a placement step of placing the liquid crystal panel (3) between the front substrate (1) and the backlight unit (4); a first positional alignment step of positionally aligning the front substrate (1) and the backlight unit (4) with each other; and a bonding step of bonding the front substrate (1), the backlight unit (4), and the liquid crystal panel (3) to one another by a first adhesive.

  • Publication number: 20090185100
    Abstract: To solve deterioration of an impact resistance caused in a thinned liquid crystal panel, a display device includes a display panel held between a transparent plate arranged on a display surface side and a plate-like member on a rear surface side in a sandwiched manner, and the transparent plate and the plate-like member are bonded and fixed to each other with an adhesive (16) in an outer periphery of the display panel.
