Abstract

Disclosed is a display device. The display device according to an aspect of the present disclosure may include: a display panel; a frame which is positioned behind the display panel, and to which the display panel is coupled; a plurality of substrates which are positioned between the display panel and the frame, on which a plurality of light sources providing light to the display panel are mounted, and which are formed of flat plates separated from each other; and a reflective sheet positioned between the display panel and the plurality of substrates, covering the plurality of substrates, and having a plurality of holes corresponding to the plurality of light sources, wherein the plurality of substrates may include: a first substrate; a second substrate next to the first substrate; and a third substrate next to the second substrate, wherein the reflective sheet may include: a first reflective sheet covering at least a portion of the first substrate and a portion of the second substrate; and a second reflective sheet covering another portion of the second substrate and at least a portion of the third substrate.

First claim

1 - 15 . (canceled)

16 . A display device comprising:
a display panel; a frame which is positioned behind the display panel, and to which the display panel is coupled; a plurality of substrates which are positioned between the display panel and the frame, on which a plurality of light sources are mounted, wherein the plurality of light sources are configured to provide light to the display panel; and a plurality of reflective sheets positioned between the display panel and the plurality of substrates, covering the plurality of substrates, and having a plurality of holes corresponding to the plurality of light sources, wherein the plurality of substrates comprise: a first substrate; a second substrate next to the first substrate; and a third substrate next to the second substrate, and wherein the plurality of reflective sheets comprise: a first reflective sheet covering at least a portion of the first substrate and a first portion of the second substrate; and a second reflective sheet separated from the first reflective sheet, and covering second portion of the second substrate and at least a portion of the third substrate.

17 . The display device of claim 16 , wherein a lateral side of the first reflective sheet crossing the second substrate faces or contacts a lateral side of the second reflective sheet crossing the second substrate.

18 . The display device of claim 17 , wherein a boundary formed between the lateral side of the first reflective sheet and the lateral side of the second reflective sheet is a straight line.

19 . The display device of claim 17 , wherein a boundary formed between the lateral side of the first reflective sheet and the lateral side of the second reflective sheet is a broken straight line.

20 . The display device of claim 16 , wherein the first reflective sheet at least partially overlaps the second reflective sheet at the second substrate.

21 . The display device of claim 16 , wherein the display panel has:
a first long side; a second long side opposite to the first long side; a first short side connecting a first end of the first long side and a first end of the second long side; and a second short side opposite to the first short side, and connecting a second end of the first long side and a second end of the second long side.

22 . The display device of claim 21 , wherein:
the first substrate is next to the first long side and the first short side of the display panel; the second substrate is next to the second long side and the first short side of the display panel; the third substrate is next to the first long side of the display panel and the first substrate; and the plurality of substrates further comprise: a fourth substrate next to the second long side of the display panel, the third substrate, and the second substrate; a fifth substrate next to the first long side of the display panel and the third substrate; a sixth substrate next to the second long side of the display panel, the fifth substrate, and the fourth substrate; a seventh substrate next to the first long side of the display panel and the fifth substrate; an eighth substrate next to the second long side of the display panel, the seventh substrate, and the sixth substrate; a ninth substrate next to the first long side of the display panel, the second short side of the display panel, and the seventh substrate; and a tenth substrate next to the second long side of the display panel, the second short side of the display panel, the ninth substrate, and the eighth substrate.

23 . The display device of claim 22 , wherein the first reflective sheet covers a boundary between the first substrate and the second substrate, a boundary between the first substrate and the third substrate, a boundary between the third substrate and the fourth substrate, and a boundary between the second substrate and the fourth substrate.

24 . The display device of claim 23 , wherein the second reflective sheet covers a boundary between the second substrate and the fourth substrate.

25 . The display device of claim 24 , wherein the plurality of reflective sheets further comprise a third reflective sheet covering a boundary between the third substrate and the fifth substrate, a boundary between the third substrate and the fourth substrate, a boundary between the fourth substrate and the sixth substrate, and a boundary between the fifth substrate and the sixth substrate.

26 . The display device of claim 25 , wherein the plurality of reflective sheets further comprise a fourth reflective sheet covering a boundary between the fourth substrate and the sixth substrate, a boundary between the sixth substrate and the eighth substrate, a boundary between the fifth substrate and the sixth substrate, and a boundary between the seventh substrate and the eighth substrate.

27 . The display device of claim 26 , wherein the plurality of reflective sheets further comprise a fifth reflective sheet covering a boundary between the seventh substrate and the ninth substrate.

28 . The display device of claim 27 , wherein the plurality of reflective sheets further comprise a sixth reflective sheet covering a boundary between the eighth substrate and the tenth substrate, a boundary between the seventh substrate and the eighth substrate, and a boundary between the ninth substrate and the tenth substrate.

29 . The display device of claim 28 , wherein a portion of the third reflective sheet overlaps a portion of the fourth reflective sheet.

30 . The display device of claim 16 , wherein a surface of the plurality of substrates on which the plurality of light sources are mounted is coated with a reflective material.
