  • Patent number: 7738244
    Abstract: A display device of the invention includes a liquid crystal display panel 1, an FPC 5, a box-formed storing case 4, and an FPC 7. The liquid crystal display panel 1 is provided with an ITO film 18 on its front side. The FPC 5 is attached to the liquid crystal display panel 1, has at least a ground line 5a, and is connected to an external device 40. The storing case 4 includes at least a rear side case (metal case) 3 electrically connected to the ITO film 18, as well as stores the liquid crystal display panel 1. The FPC 7 electrically connects the ground lines 5a of the FPC 5 and the rear side case 3. With the above-mentioned configuration, a display device can be provided wherein static protection on the front side of the display panel is easily provided.

  • Publication number: 20070164955
    Abstract: Provided is a liquid crystal display device that can be produced at low costs, can achieve miniaturization, and can offer clear virtual images. The liquid crystal display device is provided with: a frame body that is so disposed as to cover a top face of a liquid crystal cell, that has a first opening so formed as to face the top face of the liquid crystal cell, and that has a picture frame-shaped member formed around the first opening; a frame that is fixed to the frame body and that has a second opening so formed as to face a back face of the liquid crystal cell; and a light source that illuminates the liquid crystal cell via the second opening of the frame. Here, a top face of the picture frame-shaped member of the frame body is so designed that light is diffusely reflected therefrom.
