1. A display device comprising:

  • 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,wherein 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 sidewall of the frame; and

    a plurality of dots on the second sheet part, wherein the plurality of dots reduces a reflectance of light from the reflecting sheet, 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 or a second direction parallel to the short sides,wherein the plurality of dots on the second sheet part is arranged to form a first dot area, a second dot area next to the first dot area, and a third dot area next to the second dot area on the second sheet part,wherein the first dot area is a closest area to the corner of the second sheet part, the second dot area is farther from the corner of the second sheet part than the first dot area in the first direction or the second direction, and the third dot area is the farthest area from the corner of the second sheet part among the first dot area, the second dot area and the third dot area in the first direction or the second direction, andwherein a size of the dots in the first dot area is the same and is smaller than a size of the dots in the second dot area, and the size of the dots in the second dot area is the same and is smaller than a size of the dots in the third dot area, the size of the dots in the third dot area being the same.
