Abstract

A display device includes a display component, a light source, a rear side support member, and a reflective sheet. The light source is disposed on a rear side of the display device relative to the display component. The reflective sheet includes a bottom face part, a first side face part and a second side face part. The bottom face part is disposed on a front side of the display device relative to the rear side support member. The first and second side face parts are arranged relative to the bottom face part corresponding to adjacent side edges of the bottom face part, respectively. One of the first and second side face parts includes first and second portions with adjacent end sections, respectively. The adjacent end sections overlap with respect to each other while the reflective sheet is attached to the rear side support member.

First claim

What is claimed is:

1. A display device comprising:
a display panel;
a light source;
a rear side support member supporting the light source from a rear side; and
a reflective sheet that reflects light from the light source towards the display panel,
the reflective sheet including a rectangular bottom face part with four sides and four corners, a first side face part that is arranged along a first side of the four sides, and a second side face part that is arranged along a second side of the four sides that is adjacent to the first side, the first side face part including first and second portions, the first and second portions partially overlapping with respect to each other to form an overlapping portion, with the overlapping portion being entirely spaced apart from all of the corners of the bottom face part.

2. The display device according to claim 1 , wherein
the first and second portions are spaced apart from each other with a first slit therebetween, with first and second end edges of the first and second portions being adjacent to each other via the first slit.

3. The display device according to claim 2 , wherein
the first side face part is spaced apart from the bottom face part with a second slit therebetween, and
the first and second portions have first and second engagement components, respectively, that engage with the bottom face part from the rear side while the reflective sheet is attached to the rear side support member.

4. The display device according to claim 1 , wherein
the first and second portions have ear sections along outer peripheral edges of the first and second portions, respectively, the ear sections being attached to outer peripheral parts of the rear side support member while the reflective sheet is attached to the rear side support member, and
a portion of one of the ear sections is removed, with the ear sections non-overlapping with respect to each other while the first and second portions partially overlap with respect to each other.

5. The display device according to claim 1 , wherein
the first and second portions have lengths measured along outer peripheral edges of the first and second portions, respectively, the length of one of the first and second portions being larger than the length of the other of the first and second portions, and
the one of the first and second portions is disposed on a front side of the display device with respect to the other of the first and second portions while the reflective sheet is attached to the rear side support member.

6. The display device according to claim 1 , wherein
the four sides of the bottom face part includes a pair of long sides and a pair of short sides, and
the first side face part is arranged relative to the bottom face part corresponding to one of the short sides of the bottom face part.

7. The display device according to claim 6 , wherein
the reflective sheet further includes a third side face part and a fourth side face part, the first and third side face parts being oppositely arranged with respect to the bottom face part, the second and fourth side face parts being oppositely arranged with respect to the bottom face part, and
the third side face part includes third and fourth portions that are spaced apart from each other with a third slit therebetween.

8. The display device according to claim 1 , wherein
the reflective sheet has a folding portion that connects at least one of between the bottom face part and one of the first and second side face parts and between the first side face part and the second side face part.

9. The display device according to claim 8 , wherein
the folding portion includes a perforation with closed openings that are closed during formation.

10. The display device according to claim 1 , wherein
the reflective sheet is integrally formed by a sheet member as a one-piece, unitary member.

11. The display device according to claim 1 , wherein
the first and second portions partially overlap with respect to each other between adjacent corners of the corners of the bottom face part at locations spaced from the adjacent corners while the reflective sheet is attached to the rear side support member.

12. The display device according to claim 1 , wherein
the first and second portions partially overlap with respect to each other while the reflective sheet is attached to the rear side support member.

13. The display device according to claim 1 , wherein
the first side face part is entirely separated from the first side of the bottom face part.

14. A display device comprising:
a display panel;
a light source disposed on a rear side of the display device relative to the display panel;
a rear side support member supporting the light source from the rear side; and
a reflective sheet that reflects light from the light source towards the display panel,
the reflective sheet including a bottom face part, a first side face part and a second side face part, the first and second side face parts being arranged relative to the bottom face part corresponding to adjacent sides of the bottom face part, respectively, the first side face part including first and second portions, the first portion including a first end section, the second portion including a second end section that is adjacent to the first end section, the first and second end sections overlapping with respect to each other while the reflective sheet is attached to the rear side support member,
one of the first and second portions being connected to the second side face part via a folding portion, with the folding portion forming a corner of the reflective sheet while the reflective sheet is attached to the rear side support member,
the first end section having a first end edge, the second end section having a second end edge, the first and second end edges being spaced apart from the folding portion.

15. The display device according to claim 14 , wherein
the first and second portions are spaced apart from each other with a first slit therebetween, with first and second end edges of the first and second portions being adjacent to each other via the first slit.

16. The display device according to claim 15 , wherein
the first side face part is spaced apart from the bottom face part with a second slit therebetween, and
the first and second portions have first and second engagement components, respectively, that engage with the bottom face part from the rear side while the reflective sheet is attached to the rear side support member.

17. The display device according to claim 14 , wherein
the bottom face part has a rectangular shape with a pair of long sides and a pair of short sides, and
the first side face part is arranged relative to the bottom face part corresponding to one of the short sides of the bottom face part.

18. The display device according to claim 14 , wherein
the reflective sheet has a folding portion that connects at least one of between the bottom face part and one of the first and second side face parts and between the first side face part and the second side face part.
