Abstract: A display device includes: a display panel; and a backlight unit which supplies light to the display panel. The backlight unit includes: a bottom chassis; a light source module disposed along an edge portion of the bottom chassis and including a light source which generates and emits light; and a light guide which is disposed on the bottom chassis and transfers the light emitted from the light source to the display panel. At the edge portion of the bottom chassis, the light source module is disposed between the bottom chassis and the light guide to overlap the light guide, and a main light-emitting surface of the light source faces a side wall of the bottom chassis adjacent to the light source module.
