摘要：
The present invention relates to the rigidity of a backlight chassis and is applicable to a liquid crystal display device including a backlight chassis and a light source located in the backlight chassis. A liquid crystal display device according to the present invention includes a backlight chassis (24), located to face a rear surface of a liquid crystal panel (10), for supporting a light source (22) for illuminating the rear surface of the liquid crystal panel (10). The backlight chassis (24) is a substantively flat plate-like member with upright peripheral portions (24a through 24d), and includes grooves (71 through 74) in a first area (A1) and a second area (A2), which are separated from each other by a border line (L) set on the backlight chassis (24). According to the present invention, the entirety of the backlight chassis is unlikely to be deflected.
