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 first and second side face parts have first and second protrusions at adjacent end edge portions of the first and second side face parts, respectively. The first protrusion overlaps with the end edge portion of the second side face part from the rear side while the reflective sheet is attached to the rear side support member. The second protrusion overlaps with the end edge portion of the first side face part from the rear side while the reflective sheet is attached to the rear side support member.
1. A display device comprising:
a display component;
a light source disposed on a rear side of the display device relative to the display component, the light source being configured to irradiate the display component with light from the rear side;
a rear side support member supporting the light source from the rear side; and
a reflective sheet configured to reflect the light from the light source towards the display component,
the reflective sheet including a bottom face part, a first side face part and a second side face part, the bottom face part being disposed on a surface of the rear side support member while the reflective sheet is attached to the rear side support member, the first and second side face parts being disposed about the bottom face part such that the first and second side face parts define a corner of the reflective sheet while the reflective sheet is attached to the rear side support member,
the first and second side face parts having first and second protrusions at adjacent end edge portions of the first and second side face parts, respectively, the first protrusion protruding towards the end edge portion of the second side face part, the second protrusion protruding towards the end edge portion of the first side face part,
the first protrusion overlapping with the end edge portion of the second side face part from the rear side while the reflective sheet is attached to the rear side support member, the second protrusion overlapping with the end edge portion of the first side face part from the rear side while the reflective sheet is attached to the rear side support member.
2. The display device according to claim 1 , wherein
the first protrusion is disposed near a center of the end edge portion of the first side face part, and
the second protrusion is disposed at a position of the end edge portion of the second side face part other than a position corresponding to the first protrusion.
3. The display device according to claim 2 , wherein
the first side face part is configured such that the following relation (1) is satisfied:
(1/3)× A≦B ≦(2/3)× A (1)
where A is a first dimension that is measured along the end edge portion of the first side face part between an inner end of the end edge portion of the first side face part and an outer end of the end edge portion of the first side face part, and B is a second dimension that is measured along the end edge portion of the first side face part between the inner end of the end edge portion of the first side face part and an outer side edge of the first protrusion, with the outer side edge of the first protrusion being disposed farther from the bottom face part than an inner side edge of the first protrusion.
4. The display device according to claim 3 , wherein
the first side face part is further configured such that the following relation (2) in regards to the first and second dimensions is satisfied:
(1/2)× A≦B ≦(2/3)× A (2).
5. The display device according to claim 1 , wherein
the bottom face part has a rectangular shape with a long side and a short side, with the long side being longer than the short side, and
the first side face part extends from the short side of the bottom face part.
6. The display device according to claim 5 , wherein
the second side face part extends from the long side of the bottom face part.
7. The display device according to claim 1 , wherein
the first and second protrusions extend along the end edge portions of the first and second side face parts, respectively.
8. The display device according to claim 1 , wherein
the reflective sheet is integrally formed from a sheet material as a one-piece, unitary member.
9. The display device according to claim 8 , wherein
the reflective sheet is configured such that the reflective sheet does not include portions that overlap with each other while the reflective sheet is spread into a flat shape.
10. The display device according to claim 1 , wherein
the first and second protrusions are spaced apart from each other with a gap therebetween.
11. The display device according to claim 1 , wherein
the first protrusion is disposed closer to the bottom face part than the second protrusion.
