Patent number: 10613371Abstract: According to the present disclosure, a thickness of a liquid crystal display (LCD) device may be minimized by directly attaching a liquid crystal panel to a guide panel and a light guide plate made of glass through a foam pad, and thus a thin LCD device may be effectively provided. In addition, light leakage between the liquid crystal panel and the guide panel may be prevented through the foam pad including a first layer, which is a light reflecting layer, and a second layer, which is a light absorbing layer, and, at the same time, a dark portion phenomenon generated at edges of the LCD device may be effectively prevented.Type: GrantFiled: November 22, 2017Date of Patent: April 7, 2020Assignee: LG DISPLAY CO., LTD.Inventors: Se-Hyun Park, Sang-Dae Han
