Abstract: Provided is a backlight unit. The backlight unit includes a light source unit configured to emit light. A light guide plate is configured to receive the light emitted from the light source unit. A bottom chassis accommodates the light source unit and the light guide plate. The bottom chassis includes a bottom surface, a sidewall extending from the bottom surface, and an extension part extending from the sidewall. The extension part overlaps substantially an entire upper surface of the light source unit and at least a portion of an upper surface of the light guide plate. The extension part includes an upper surface and a light reflection surface disposed closer to the light guide plate than the upper surface. An uneven pattern is formed on the light reflection surface.
