Abstract

A backlight assembly includes at least one lamp including a lamp electrode, at least one lamp socket holding the lamp, an inverter applying electric power to the lamp, and a receiving container including a socket receiving portion corresponding to an end portion of the lamp to receive the lamp socket and an inverter receiving portion for receiving the inverter. Therefore, a manufacturing process may be simplified, and manufacturing costs is decreased.

Claims (25)

1. A backlight assembly comprising:

at least one lamp including a lamp electrode;

at least one lamp socket holding the lamp;

an inverter applying electric power to the lamp; and

a receiving container comprising a socket receiving portion corresponding to an end portion of the lamp to receive the lamp socket, and an inverter receiving portion for receiving the inverter,

wherein the socket receiving portion is formed at an extended sidewall that protrudes from an upper side of a longitudinal sidewall; wherein the longitudinal sidewall protrudes from a longitudinal edge of a bottom plate of the receiving container.

2. The backlight assembly of claim 1 , wherein the socket receiving portion is separated from the inverter receiving portion by a separating bar extended from an end portion of the longitudinal sidewall.

3. The backlight assembly of claim 2 , wherein the socket receiving portion further comprises a stepped portion on a side surface facing the lamp socket; and wherein the lamp socket is combined with the socket receiving portion through a sliding combination.

4. The backlight assembly of claim 3 , wherein the socket receiving portion further comprises a hook portion on the stepped portion to hold the lamp socket.

5. The backlight assembly of claim 1 , wherein the socket receiving portion is separated from the inverter receiving portion by a protruded portion that protrudes from an end portion of the longitudinal sidewall.

6. The backlight assembly of claim 5 , wherein the socket receiving portion further comprises a stepped portion on a side surface facing the lamp socket so that the lamp socket is combined with the socket receiving portion in a vertical direction.

7. The backlight assembly of claim 6 , wherein the socket receiving portion further comprises a hook portion on the stepped portion to hold the lamp socket.

8. The backlight assembly of claim 1 , wherein a hole for dissipating heat generated from the inverter is formed through the bottom plate.

9. The backlight assembly of claim 8 , wherein the receiving container comprises a combining portion through which the receiving container is combined with a bottom chassis.

10. The backlight assembly of claim 9 , wherein the combining portion is formed on an opposite longitudinal sidewall adjacent to corners of the receiving container, and the opposite longitudinal sidewall faces the longitudinal sidewall adjacent to the socket receiving portion.

11. The backlight assembly of claim 10 , wherein a window is formed on a horizontal sidewall of the receiving container to dissipate heat generated from the inverter.

12. The backlight assembly of claim 1 , wherein the lamp socket comprises a lamp holding part electrically connected to the lamp electrode and an inverter holding part on a lower portion of the lamp socket to receive electric power for driving the lamp.

13. A liquid crystal display (LCD) device comprising:

an LCD panel displaying an image; and

a backlight assembly supplying the LCD panel with light, the backlight assembly comprising:

at least one lamp comprising a lamp electrode;

at least one lamp socket holding the lamp electrode;

an inverter applying electric power to the lamp; and

a receiving container including a socket receiving portion corresponding to an end portion of the lamp to receive the lamp socket, and an inverter receiving portion for receiving the inverter,

wherein the socket receiving portion is formed at an extended sidewall that protrudes from an upper side of a longitudinal sidewall; wherein the longitudinal sidewall protrudes from a longitudinal edge of a bottom plate of the receiving container.
