Abstract: Disclosed herein are a backlight unit and a display device including the same. The backlight unit can reduce the number of light sources and can uniformly supply light to a region in which the light sources are disposed and a region in which the light sources are not disposed by arranging a reflective pattern on an upper surface of each light source to emit the light through a side portion of the light source and allowing the emitted light to travel by a light guide portion connecting between the light sources to be emitted above the light guide portion by a reflective layer positioned in a region between the light sources.
