Abstract

Disclosed are a backlight assembly and an LCD apparatus that includes the backlight assembly. A first receiving container has at least two members that can be combined into a frame and receive a plurality of lamps and a light diffusing member. A receiving container may be fabricated using the two or more members. Even though the size of the frame made of the members is small relative to the LCD apparatus, the receiving container can be used with the LCD apparatus. Accordingly, manufacturing processes of the LCD apparatus may be simplified and cost of production may be reduced.

Claims (20)

1. A backlight assembly comprising:

a lamp generating a light;

an optical member disposed over the lamp, the optical member guiding the light; and

a receiving container receiving the lamp and the optical member, the receiving container including:

a first receiving container including a first member having a first main portion and a second main portion extending from a first end of the first main portion in a direction substantially perpendicular to the first main portion, and a second member having a third main portion substantially parallel to the first main portion and a fourth main portion extending from a first end of the third main portion in a direction substantially perpendicular to the third main portion, the second member being separably coupled to both ends of the first member, and

a second receiving container having a bottom plate and sidewalls extended from edges of the bottom plate to form a receiving space, the second receiving container receiving the first receiving container in the receiving space,

wherein the first member further comprising:

a first engaging portion extended from an end of the second main portion in a direction substantially parallel to the first main portion, the first engaging portion being coupled to a second end of the third main portion, and

wherein the second member further comprising:

a second engaging portion extending from an end of the fourth main portion in a direction substantially parallel to the third main portion, the second engaging portion being coupled to a second end of the first main portion.

2. The backlight assembly of claim 1 , wherein the first engaging portion of the first main portion is recessed from an upper surface of the first main portion.

3. The backlight assembly of claim 2 , wherein the first engaging portion of the first main portion overlaps with the second engaging portion of the third main portion.

4. The backlight assembly of claim 3 , wherein the first engaging portion of the first main portion is combined with the second engaging portion of the third main portion with screws.

5. The backlight assembly of claim 4 , wherein the first main portion and the third main portion is coupled together without forming a stepped portion.

6. The backlight assembly of claim 1 , wherein the lamp has first and second lamp ends, and the first and second lamp ends are coupled to the first receiving container.

7. The backlight assembly of claim 6 , further comprising a lamp holder receiving the first lamp end, at least one of the members of the first receiving container having a lamp receiving groove receiving the lamp holder.

8. The backlight assembly of claim 1 , wherein the optical member comprises:

a diffusing plate disposed on the first receiving container to diffuse the light generated from the lamp;

an optical sheet disposed on the diffusing plate to increase optical properties for the diffused light, the optical sheet having a body portion and a fixing portion that protrudes from the body portion, and

fixing protrusion disposed on the members of the first receiving container to fix the optical sheet to the members of the first receiving container, the fixing protrusions being inserted into a fixing hole formed through the fixing portion of the optical sheet.
