Abstract: Discussed are a backlight unit and an autostereoscopic 3D (three-dimensional) display device including the same, in which a 3D image can be displayed without using a 3D light controller that includes a liquid crystal layer. The backlight unit may include a 3D light guide plate having first light output patterns, first light sources irradiating light to at least one side of the 3D light guide plate, a 2D (two-dimensional) light guide plate arranged below the 3D light guide plate, and second light sources irradiating light to at least one side of the 2D light guide plate. The first light output patterns are a plurality of line prism patterns spaced apart from each other.
