1. A liquid crystal display device comprising:
a lower receiving container;
a plurality of supporting walls arranged in a line along at least one side wall of the lower receiving container with gaps therebetween;
a plurality of light sources arranged in a line so as to be provided in the gaps;
a reflecting sheet positioned on the lower receiving container and under the light sources; and
a reflecting cover covering at least a portion of each of the gaps, the reflecting cover having a body made of the same material as that of the reflecting sheet.
2. The liquid crystal display device of claim 1 , wherein:
each of the supporting walls includes:
a supporting wall upper surface; and
a supporting wall inclined plane that extends from the supporting wall upper surface to the bottom of the lower receiving container and has a first length.
3. The liquid crystal display device of claim 2 , wherein the reflecting cover is provided on the plurality of supporting walls, and extends in a direction in which the plurality of supporting walls are arranged so as to cover all the supporting walls and all the gaps.
4. The liquid crystal display device of claim 3 , wherein the reflecting cover comprises a reflective material.
5. The liquid crystal display device of claim 4 , wherein:
the reflecting cover includes:
a reflecting cover upper surface that covers the supporting wall upper surfaces; and
a reflecting cover inclined plane that extends from the reflecting cover upper surface and has a second length smaller than the first length.
6. The liquid crystal display device of claim 4 , wherein:
the reflecting cover includes:
a reflecting cover upper surface that covers the supporting wall upper surfaces;
a reflecting cover inclined plane that extends from the reflecting cover upper surface and has a third length substantially equal to the first length; and
light source insertion holes that are formed at positions corresponding to the light sources.
7. The liquid crystal display device of claim 2 , wherein the reflecting cover extends from one side surface of one supporting wall to another supporting wall among the plurality of supporting walls.
8. The liquid crystal display device of claim 7 , wherein the reflecting cover is made of the same material as that forming the supporting walls and has elasticity.
9. The liquid crystal display device of claim 7 , wherein the width of the reflecting cover is substantially equal to the gap between the supporting walls.
10. The liquid crystal display device of claim 2 , further comprising:
an optical sheet mounted on the supporting wall upper surface.
11. The liquid crystal display device of claim 1 , further comprising:
an intermediate receiving container that is provided above the lower receiving container and is made of a non-reflective resin,
wherein the supporting walls and the lower receiving container are made of a light reflective resin.
12. The liquid crystal display device of claim 11 , wherein the intermediate receiving container has a black-based color.
13. The liquid crystal display device of claim 11 , wherein the supporting walls and the lower receiving container are integrally formed.
14. The liquid crystal display device of claim 11 , wherein:
another side wall of the lower receiving container that is vertical to one side wall includes a reflective lower receiving container inclined plane, and
no reflecting member is provided between the light sources and the bottom and the lower receiving container inclined plane of the lower receiving container.
15. The liquid crystal display device of claim 1 , wherein:
a space is formed between the plurality of supporting walls and the side wall of the lower receiving container, and
the ends of the plurality of light sources are arranged in the space.
16. A liquid crystal display device comprising:
a lower receiving container;
a plurality of supporting walls arranged in a line along at least one side wall of the lower receiving container with gaps therebetween;
a plurality of light sources arranged in a line so as to be provided in the gaps;
a reflecting sheet positioned on the lower receiving container and under the light sources;
a reflecting cover covering at least a portion of each of the gaps, the reflecting cover having a body made of the same material as that of the reflecting sheet; and
an intermediate receiving container provided above the lower receiving container and made of a non-reflective resin,
wherein each of the supporting walls includes:
a supporting wall upper surface; and
a supporting wall inclined plane that extends from the supporting wall upper surface to the bottom of the lower receiving container and has a first length.
17. The liquid crystal display device of claim 16 , wherein the reflecting cover comprises a reflective material.
18. The liquid crystal display device of claim 17 , wherein:
the reflecting cover includes:
a reflecting cover upper surface that covers the supporting wall upper surfaces; and
a reflecting cover inclined plane that extends from the reflecting cover upper surface and has a second length smaller than the first length.
19. The liquid crystal display device of claim 16 , wherein:
another side wall of the lower receiving container that is vertical to one side wall includes a reflective lower receiving container inclined plane, and
no reflecting member is provided between the light sources and the bottom and the lower receiving container inclined plane of the lower receiving container.
20. The liquid crystal display device of claim 16 , wherein:
a space is formed between the plurality of supporting walls and the side wall of the lower receiving container, and
the ends of the plurality of light sources are arranged in the space.
