Abstract: According to one embodiment, a backlight includes a light source, a light guide plate provided laterally to the light source to convert light from the light source into planar light, and multiple optical sheets provided in a laminated manner between the light guide plate and a liquid crystal panel. A liquid crystal display device includes a frame surrounding and holding the liquid crystal panel and the backlight. The frame includes fitted portions recessed in positions opposed to the optical sheets. The optical sheets each include protrusions provided on both sides close to the light source to be fitted into the respective fitted portions. The optical sheets each further include a stuck portion provided on the side near the light source and stuck to a double-sided adhesive tape.

Abstract: According to one embodiment, a light guide plate includes a light guide plate main body disposed with one end side thereof opposed to a light source and convex portions provided on the both lateral portions in positions separate from the both end portions toward the center of the light guide plate main body. A frame includes fitted portions recessed in positions corresponding to the respective convex portions, into which the convex portions are to be fitted. A bonding member bonds the fitted portions and the convex portions fitted into the respective fitted portions and serves as a light-blocking member covering the interior of the fitted portions and the exterior of the convex portions.
