Abstract

A display device includes a display portion, a light source, and a reflector. The reflector reflects light from the light source. The reflector has a rectangular bottom part, first and second peripheral parts that partially extend from first opposing sides of the bottom part, and third and fourth peripheral parts that extend from second opposing sides of the bottom part that are adjacent to the first opposing sides. The first and second peripheral parts and the third and fourth peripheral parts have overlapping regions that overlap each other.

First claim

What is claimed is:

1. A display device comprising:
a display portion;
a light source; and
a reflector that reflects light from the light source,
the reflector having a rectangular bottom part, first and second peripheral parts that partially extend from first opposing sides of the bottom part, and third and fourth peripheral parts that extend from second opposing sides of the bottom part that are adjacent to the first opposing sides, the first and second peripheral parts and the third and fourth peripheral parts having overlapping regions that overlap each other, with the overlapping regions being entirely spaced apart from all of corners of the bottom part.

2. The display device according to claim 1 , wherein
the first and second peripheral parts have the overlapping regions at one or two locations, respectively.

3. A display device comprising:
a display portion;
a light source; and
a reflector that reflects light from the light source,
the reflector having a rectangular bottom part, first and second peripheral parts that partially extend from first opposing sides of the bottom part, and third and fourth peripheral parts that extend from second opposing sides of the bottom part that are adjacent to the first opposing sides, the first and second peripheral parts and the third and fourth peripheral parts having overlapping regions that overlap each other,
the first and second peripheral parts being located at middle portions of the first opposing sides.

4. The display device according to claim 1 , wherein
the first and second peripheral parts are located at end portions of the first opposing sides.

5. The display device according to claim 1 , wherein
at least one of the third and fourth peripheral parts extends from an entire portion of corresponding one of the second opposing sides.

6. The display device according to claim 5 , wherein
the third and fourth peripheral parts have first sections that extend from the second opposing sides, and second sections that extend from the first sections,
the second sections overlap with the first and second peripheral parts.

7. The display device according to claim 1 , wherein
the third and fourth peripheral parts have first sections that extend from the second opposing sides, and second sections that extend from the first sections,
the second sections overlap with the first and second peripheral parts.

8. The display device according to claim 7 , wherein
the second sections overlap with the bottom part.

9. The display device according to claim 7 , wherein
the second sections extend from both ends of each of the first sections.

10. A display device comprising:
a display portion;
a light source; and
a reflector that reflects light from the light source,
the reflector including a rectangular bottom portion and peripheral portions that extend from opposing sides of the bottom portion, respectively, the reflector having first overlapping regions in which parts of the reflector overlap with each other, with the first overlapping regions being disposed at the peripheral portions, respectively, with the first overlapping regions being entirely spaced apart from all of corners of the bottom portion.

11. The display device according to claim 10 , wherein
each of the first overlapping regions is disposed outward relative to corresponding one of the opposing sides.

12. The display device according to claim 10 , wherein
the first overlapping regions are disposed at two locations for each of the peripheral portions.

13. The display device according to claim 12 , wherein
the two locations are spaced apart from each other along corresponding one of the opposing sides.

14. The display device according to claim 10 , wherein
the reflector further having second overlapping regions in which parts of the reflector overlap with each other, with the second overlapping regions being disposed at the bottom portion.

15. The display device according to claim 14 , wherein
the second overlapping regions extend along the opposing sides, respectively.

16. The display device according to claim 15 , wherein
the second overlapping regions extend from the corners of the bottom portion, respectively.

17. The display device according to claim 14 , wherein
the second overlapping regions are disposed at two locations for each of the opposing sides.

18. The display device according to claim 17 , wherein
the two locations are spaced apart from each other along corresponding one of the opposing sides.

19. The display device according to claim 10 , wherein
the first overlapping regions have a triangular shape.

20. The display device according to claim 14 , wherein
the second overlapping regions have a triangular shape.
