Abstract: A back light assembly includes: a light source including a light emitting diode which generates white light having color coordinates located on one of a plurality of color coordinate ranks; a reflector sheet which reflects the white light incident from the light source, where the reflector sheet includes a reflective material which reflects light incident thereon and a color compensation material which compensates the color coordinates of the white light by controlling the intensity of light having a predetermined wavelength range, among the white light, to allow the color coordinates of the white light to converge on target color coordinates; and a diffuser plate which diffusing light provided from the light source and the reflector sheet.

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.
