Abstract

The inventive concepts provides a liquid crystal display having advantages of being capable of simplifying a manufacturing method thereof and minimizing damage to internal components therein by using a bottom chassis in which a flange unit and a receiver of a backlight unit are separated from each other. In accordance with the inventive concepts, the bottom chassis is formed in such a shape so as to be assembled and disassembled. Accordingly, it is possible to securely couple the flange unit to any necessary portions of the receiver, thereby reducing an effort and cost for mold development. Further, a gap between the receiver and the flange unit is formed to provide a predetermined degree of flexibility. Therefore, when the display device is assembled, deformation of the entire bottom chassis caused by deformation of the flange unit may be prevented.

Claims

1. A liquid crystal display comprising:

a liquid crystal panel configured to display an image;

a backlight unit configured to supply light to the liquid crystal panel; and

a bottom chassis configured to accommodate the backlight unit, the bottom chassis including a bottom portion, a receiver extending substantially perpendicular to the bottom portion and including a first coupler disposed on a surface of the receiver, and a flange unit including a second coupler coupled to the first coupler,

wherein the flange unit extends in a first direction which is substantially perpendicular to the receiver and the bottom portion extends in a second direction which is substantially perpendicular to the receiver and opposite to the first direction.

2. The liquid crystal display of claim 1, wherein the first coupler is formed in a convex or concave shape, and

the second coupler is formed in a concave or convex shape corresponding to the coupler of the receiver.

3. The liquid crystal display of claim 2, wherein the first coupler is formed on an inner surface of a side surface of the receiver.

4. The liquid crystal display of claim 3, wherein the first coupler is formed on every inner surface of the receiver and is formed along an entire inner surface.

5. The liquid crystal display of claim 3, wherein the first coupler is formed on at least one side surface of the receiver and is formed along an entire inner surface.

6. The liquid crystal display of claim 3, wherein the first coupler is divided into at least two parts and is formed on a portion of a side surface of the receiver.

7. The liquid crystal display of claim 2, wherein the flange unit has a fastening hole configured to be coupled to the display device.

8. The liquid crystal display of claim 7, wherein the first coupler is formed on an entire surface of the receiver to which the flange unit is coupled.

9. The liquid crystal display of claim 7, wherein the second coupler is divided into two parts.

10. The liquid crystal display of claim 2, wherein the first coupler and the second coupler are formed in a circularly concave or convex shape.

11. The liquid crystal display of claim 2, wherein the first coupler and the second coupler are formed in a triangularly concave or convex shape.

12. The liquid crystal display of claim 2, wherein the first coupler and the second coupler are formed in a quadrangularly concave or convex shape.

13. The liquid crystal display of claim 1, wherein the receiver and the flange unit provide flexibility when they are coupled to each other.

14. A liquid crystal display including a display area configured to display an image and a bezel surrounding the display area, the liquid crystal display comprising:

a liquid crystal panel;

a backlight unit configured to supply light to the liquid crystal panel; and

a bottom chassis configured to accommodate the backlight unit, the bottom chassis including a bottom portion, a receiver extending substantially perpendicular to the bottom portion and including a first coupler disposed on an inner surface of the receiver, and a flange unit including a second coupler separably coupled to the first coupler and a fastening hole configured to couple with an external structure in a bezel area,

wherein the flange unit extends in a first direction which is substantially perpendicular to the receiver and the bottom portion extends in a second direction which is substantially perpendicular to the receiver and opposite to the first direction.

15. The liquid crystal display of claim 14, wherein the first coupler has a portion in which the second coupler is not coupled.

16. The liquid crystal display of claim 15, wherein the first coupler is formed on every inner surface of the receiver and is formed along an entire inner surface.

17. The liquid crystal display of claim 16, wherein the first coupler and the second coupler are formed in a circularly concave or convex shape.

18. The liquid crystal display of claim 16, wherein the first coupler and the second coupler are formed in a triangularly concave or convex shape.

19. The liquid crystal display of claim 16, wherein the first coupler and the second coupler are formed in a quadrangularly concave or convex shape.

20. The liquid crystal display of claim 15, wherein the first coupler is formed on at least one side surface of the receiver and is formed along an entire inner surface.
