Publication number: 20050062899Abstract: A defective display is obviated by preventing the intrusion of a foreign substance in a gap defined between a constitutional member, such as an upper frame, an intermediate frame, a backlight device or the like, and a display panel and by suppressing the application of a stress to the display panel. A shaped elastic member is interposed between a liquid crystal display panel and a mold of a backlight device. One longitudinal side surface of the shaped elastic member is fixedly mounted on the backlight device and the other longitudinal side surface of the shaped elastic member is non-fixedly mounted on the liquid crystal display panel, such that the other longitudinal side surface is always brought into contact with the liquid crystal display panel to prevent the generation of a gap therebetween.Type: ApplicationFiled: September 16, 2004Publication date: March 24, 2005Inventors: Norihisa Fukayama, Kazuyoshi Tanaka
