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.

Abstract: Embodiments of the disclosure are related to a backlight unit and a display device, by disposing a filter reflecting a green light of a long wavelength on a color conversion sheet and disposing a filter reflecting a green light and a red light under the color conversion sheet, a wavelength band of a light supplied to a display panel is controlled and a color reproduction range may be improved while increasing a light efficiency. Furthermore, by disposing a sheet increasing an amount of a vertical light on the color conversion sheet, a wavelength band of a light reflected by a filter disposed on the color conversion sheet is controlled exactly and the backlight unit and the display device capable of a wide color gamut may be provided.
