BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY HAVING THE SAME

摘要

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.
