Abstract: A backlight unit and a display device including the same are provided. The backlight unit includes: a frame; a reflection sheet located on the frame; a housing coupled to at least one side of the frame; a substrate located on the housing; a light assembly mounted on the substrate; and a light guide plate located opposite to the light assembly on the reflection sheet, wherein the housing is exposed to the outside of the frame. Therefore, as the housing is exposed to the outside of the frame, even if a problem occurs in a light assembly, by separating only the housing, the problem can be solved, and the housing is exposed to the outside of the frame to enhance a heat releasing effect.
