摘要： Provided is a backlight unit of a liquid crystal display (LCD). The backlight unit includes: a plurality of light guide plates (LGPs) arranged in M layers and separated from each other by a predetermined gap, wherein M is a natural number equal to or greater than two, a light source unit disposed on at least one side surface of each of the LGPs and including N light source blocks whose brightnesses are controlled individually, and wherein N is a natural number equal to or greater than two. The backlight unit further includes a plurality of light output regions defined by each of the LGPs being divided into a plurality of regions according to a distance from the light source unit and by a plurality of light output patterns being formed in some of the regions, and wherein the light output regions do not overlap each other in a stacking direction of the LGPs and are arranged to correspond to a whole surface of the LGPs.
