Abstract

A display device is disclosed. The display device includes a display panel; a first substrate positioned in a rear of the display panel; a second substrate positioned in the rear of the display panel and adjacent to the first substrate; a plurality of first light sources mounted on the first substrate and configured to provide light to the display panel; a plurality of second light sources mounted on the second substrate and configured to provide light to the display panel; and a first reflective sheet positioned on the first substrate, the first reflective sheet including a plurality of first holes formed corresponding to positions of the plurality of first light sources, wherein in the plurality of first holes, an area of a first hole formed corresponding to a position of a first light source close to a boundary of the first substrate and the second substrate may be greater than an area of a second hole formed corresponding to a position of a second light source far from the boundary of the first substrate and the second substrate.

Claims (22)

1. A display device comprising:

a display panel;

a first substrate positioned in a rear of the display panel;

a second substrate positioned in the rear of the display panel and adjacent to the first substrate;

a plurality of first light sources mounted on the first substrate and configured to provide light to the display panel;

a plurality of second light sources mounted on the second substrate and configured to provide light to the display panel; and

a first reflective sheet positioned on the first substrate, the first reflective sheet including a plurality of first holes formed corresponding to positions of the plurality of first light sources,

wherein in the plurality of first holes, an area of a first hole formed corresponding to a position of a first light source close to a boundary of the first substrate and the second substrate is greater than an area of a second hole formed corresponding to a position of a second light source far from the boundary of the first substrate and the second substrate.

2. The display device of claim 1 , further comprising a second reflective sheet positioned on the second substrate, the second reflective sheet including a plurality of second holes formed corresponding to positions of the plurality of second light sources,

wherein in the plurality of second holes, an area of a third hole formed corresponding to a position of a third light source close to the boundary of the first substrate and the second substrate is greater than an area of a fourth hole formed corresponding to a position of a fourth light source far from the boundary of the first substrate and the second substrate.

3. The display device of claim 2 , wherein a first direction parallel to the boundary of the first substrate and the second substrate and a second direction perpendicular to the first direction are defined,

wherein along the second direction, a distance between the first light source and the second light source is greater than a distance between the first light source and the third light source.

4. The display device of claim 3 , wherein along the second direction, a distance between the third light source and the fourth light source is greater than a distance between the third light source and the first light source.

5. The display device of claim 4 , wherein along the first direction, a distance between the first light source and the second light source is the same as a distance between the first light source and the third light source.

6. The display device of claim 5 , wherein along the first direction, a distance between the third light source and the fourth light source is the same as a distance between the third light source and the first light source.

7. The display device of claim 6 , wherein the first hole or the third hole includes:

a first part extending in the first direction; and

a second part extending in the second direction.

8. The display device of claim 7 , wherein a length of the first part is greater than a length of the second part.

9. The display device of claim 8 , wherein the first light source is positioned in the second part of the first hole,

wherein the third light source is positioned in the second part of the third hole.

10. The display device of claim 8 , wherein a shape of the first hole is symmetrical to a shape of the third hole with respect to the boundary of the first substrate and the second substrate.
