Abstract

A backlight assembly includes an optical unit including a lamp unit emitting light. The backlight assembly also includes a receiving container. The receiving container includes a plurality of side walls, a bottom plate separably combined with the side walls, and a combining element for combining the side walls with the bottom plate. The receiving container receives the optical unit in a receiving space defined by the side walls, the bottom plate, and the combining element.

Claims (30)

1. A backlight assembly comprising:

an optical unit including a lamp unit which emits light; and

a receiving container including a plurality of side walls, a bottom plate having a plate shape, the bottom plate being separable, non-unitary and divisible from the side walls and combined with the side walls, and a combining element which combines the side walls with the bottom plate, wherein the receiving container receives the optical unit in a receiving space defined by the side walls, the bottom plate and the combining element.

2. The backlight assembly of claim 1 , wherein the side walls and the bottom plate are formed from substantially the same material.

3. The backlight assembly of claim 2 , wherein the side walls and the bottom plate are formed from a metallic material.

4. The backlight assembly of claim 1 , wherein the side walls are formed from a material that is different than a material used to form the bottom plate.

5. The backlight assembly of claim 4 , wherein the side walls are formed from a metallic material, and the bottom plate is formed from a polymer material.

6. The backlight assembly of claim 1 , wherein the side walls are integrally formed.

7. The backlight assembly of claim 1 , wherein the side walls are formed separately from each other and assembled to define the receiving space.

8. The backlight assembly of claim 1 , wherein the bottom plate is formed by assembling a plurality of plates.

9. The backlight assembly of claim 8 , wherein an opening portion is formed on the bottom plate.

10. The backlight assembly of claim 1 , wherein the receiving container further comprises a lamp unit supporting element having a fixing groove for fixing the lamp unit and a protrusion supporting a diffusion plate, and the lamp unit supporting element is combined with the bottom plate.

11. The backlight assembly of claim 10 , wherein the lamp unit supporting element is integrally formed with the bottom plate.

12. The backlight assembly of claim 1 , wherein the receiving container further comprises a lamp unit supporting element having a fixing groove for fixing the lamp unit, and the lamp unit supporting element is combined with the bottom plate and the side walls.

13. The backlight assembly of claim 12 , wherein the lamp unit supporting element is integrally formed with the bottom plate.

14. A liquid crystal display (LCD) apparatus comprising:

a backlight assembly which supplies light;

a display unit disposed over the backlight assembly; and

a first receiving container which fixes the display unit,

wherein the backlight assembly comprises:

an optical unit including a lamp unit which emits the light; and

a second receiving container including a plurality of side walls, a bottom plate having a plate shape, the bottom plate being separable, non-unitary and divisible from the side walls and combined with the side walls, and a combining element which combines the side walls with the bottom plate, wherein the second receiving container receives the optical unit in a receiving space defined by the side walls, the bottom plate and the combining element.

15. The LCD apparatus of claim 14 , wherein the side walls and the bottom plate are formed from substantially the same metallic material.

16. The LCD apparatus of claim 14 , wherein the side walls are formed from a material that is different than a material used to form the bottom plate.

17. The LCD apparatus of claim 16 , wherein the side walls are formed from a metallic material, and the bottom plate is formed from a polymer material.

18. The LCD apparatus of claim 14 , wherein the second receiving container further comprises a lamp unit supporting element having a fixing groove for fixing the lamp unit, and a protrusion supporting a diffusion plate, and the lamp unit supporting element is combined with the bottom plate.

19. The LCD apparatus of claim 18 , wherein the lamp unit supporting element is integrally formed with the bottom plate.

20. A method for manufacturing a backlight assembly, the method comprising:

combining a plurality of side walls with a bottom plate, which is separable, non-unitary and divisible from the side walls, by a combining element; and

disposing an optical unit in a receiving space that is defined by the side walls, the bottom plate and the combining element.
