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.

Abstract: A light guide plate receives light and guides the light to a display panel. The light guide plate includes a body and protruding portions. The body includes a first side surface disposed adjacent to the light source, a second side surface facing the first side surface, and an upper surface. Protruding portions are protruded from the upper surface. Each of the protruding portions includes first and second protruding portions sequentially arranged from the first side surface to the second side surface. A width of the first protruding portion in a direction substantially parallel to the first side surface becomes smaller as a distance from the first side surface becomes larger, and a width of the second protruding portion in the direction substantially parallel to the first side surface becomes larger as the distance from the first side surface becomes larger.
