摘要： A backlight unit and a two-dimensional (2D) and three-dimensional (3D) image display system including the same. The backlight unit includes a first light guide plate and a second light guide plate, wherein the first light guide plate includes a plurality of first diffusion units that are aligned to be spaced apart from each other, and the second light guide plate includes a plurality of second diffusion units that are aligned alternately with the first diffusion units. Thus, an emission direction of light is controlled, so that a 3D image may be displayed in a plurality of viewing zones.
