  • Patent number: 8305334
    Abstract: The invention provides a liquid crystal display device which can reduce the manufacturing cost by reducing the number of parts and simplifying the fabrication and the assembling operation, for the conduction between a metal frame and a color filter substrate. A liquid crystal display panel has a conductive layer on a front surface of a second glass substrate. A panel frame has a side wall part extending along a side wall of the liquid crystal display panel and an upper surface part extending from the side wall part toward a front surface direction of the liquid crystal display panel, integrally formed together. The upper surface part is in contact with the conductive layer of the liquid crystal display panel. A constant potential is applied to the panel frame.

  • Publication number: 20080055513
    Abstract: The present invention provides a liquid crystal display module which can prevent an external force from ill-affecting the display even when the external force is applied to the liquid crystal display module. In the liquid crystal display module according to the invention which includes a liquid crystal display panel, a light guide plate and a mold which are arranged on a back surface of the liquid crystal display panel, a metal-made lower frame which is arranged on a light-guide-plate-and-mold side, and a metal-made upper frame which is arranged on a liquid-crystal-display-panel side, a thickness of the lower frame is set larger than a thickness of the upper frame. The thickness of the lower frame is preferably set 1.33 times or more and 2.66 times or less as large as the thickness of the upper frame.
