Patent number: 8681293Abstract: Provided is a liquid crystal display device in which uneven brightness in a side-light type backlight unit is reduced, the uneven brightness being generated through reflection of light from a light source at an interface of an engaging cutout portion for preventing a light guide plate from shifting. A light guide plate (60) includes a cutout portion (82) through which a light guide plate support pin (80) provided upright to a lower frame fitting is inserted, at a lower side adjacent to a left side at which a light bar (64) is arranged. Further, at the lower side, a cutout portion (84) having a shallower recess than that of the cutout portion (82) and positioned in front of the cutout portion (82) when viewed from the light bar (64) is provided.Type: GrantFiled: September 12, 2012Date of Patent: March 25, 2014Assignee: Panasonic Liquid Crystal Display Co., Ltd.Inventors: Hiroshi Obata, Makoto Fujimoto, Shunsuke Morishita, Naruhiro Matsumoto
