| description | 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. |
