Abstract
A display device including a display panel; a frame at a rear of the display panel, the frame including a bottom and a sidewall extending from the bottom; a substrate on the frame; a plurality of light sources mounted on the substrate; and a reflecting sheet on the substrate. The reflecting sheet includes a first sheet part on the bottom and having a rectangular shape with a first long side, a second long side opposite the first long side, a first short side adjacent to the first long side and the second long side, and a second short side opposite the first short side, the first sheet part comprising a plurality of holes corresponding to the plurality of light sources; a second sheet part extended from the first sheet part toward the side wall of the frame; and a plurality of dots on the second sheet part, wherein the plurality of dots reduces a reflectance of light, and wherein a size of the plurality of dots increases from a corner of the second sheet part in a first direction parallel to the long sides and a second direction parallel to the short sides.
