    摘要： A backlight unit and a display device including the same are disclosed. The backlight unit includes a frame including a bottom area and a sidewall area extended from the bottom area, at least one substrate positioned at a front surface of the frame, a plurality of light sources being mounted on the at least one substrate, a reflective sheet positioned at a front surface of the at least one substrate, and an optical sheet positioned at a front surface of the reflective sheet. The reflective sheet includes a first sheet area contacting the bottom area and including a plurality of lens holes, and a second sheet area spaced apart from the bottom area and including a dot area. The dot area includes a first dot area and a second dot area spaced apart from the first dot area.

    摘要： Disclosed herein are a backlight unit and a display device using the same. In an embodiment, the backlight unit includes a substrate, at least one light source on the substrate, a lenses placed over the light source, a reflection sheet in which at least one through hole corresponding to the lens is formed, and a reflection ring comprising an opening portion corresponding to the at least one light source, and placed between the lens and the substrate. In accordance with an embodiment of the present invention, luminance uniformity of the backlight unit can be improved because the reflection ring surrounding the light source is included.
