Abstract

A liquid crystal display (LCD) device includes an LCD panel to display images, a backlight unit to supply light to the LCD panel, a frame provided with an inverter to supply an alternating current of a high voltage to the lamp, and an inverter cover engaged with the frame to receive the inverter.

Claims (29)

1. A liquid crystal display (LCD) device, comprising:

an LCD panel to display image;

a backlight unit to supply light to the LCD panel;

a frame provided with an inverter to supply an alternating current to the backlight unit, wherein the frame includes first supports to support an inverter cover in a thickness direction, and second supports between the first supports to support the inverter cover in a retreat direction, and wherein the inverter cover includes first hooks corresponding to the first supports to be engaged with the frame in a thickness direction, and a second hook corresponding to the second supports to be engaged with the frame in a retreat direction so that the first hooks of the inverter cover are inserted into the first supports and the second hook of the inverter cover is supported in the bottom support by the second supports; and

wherein the inverter cover is engaged with the frame to receive the inverter.

2. The LCD device as claimed in claim 1 , wherein the frame includes at least one first support, and the inverter cover includes at least one first hook that is inserted into the at least one first support or the frame.

3. The LCD device as claimed in claim 2 , wherein the first hook is stepped to limit an insertion depth of the inverter cover.

4. The LCD device as claimed in claim 1 , wherein the frame includes at least one second support protruded in a thickness direction, and the inverter cover includes at least one second hook cut in a slit shape, such that the at least one second hook is engaged with the second support of the frame.

5. The LCD device as claimed in claim 4 , wherein the second support is inclined in an entry direction of the inverter cover.

6. A liquid crystal display (LCD) device, comprising:

an LCD panel to display images;

a backlight unit to supply light to the LCD panel;

a bottom support provided with an inverter to supply an alternating current to the backlight unit, wherein the bottom support includes first supports to support an inverter cover in a thickness direction, and second supports protruded between the first supports so that the inverter cover is hooked and supported in the second support; and

wherein the inverter cover is engaged with the bottom support to receive the inverter, and the inverter cover includes first hooks corresponding to the first supports to be engaged in the bottom support and a second hook corresponding to the second supports in a slit shape between the first hooks so that the first hooks of the inverter cover are inserted into the first supports and the second hook of the inverter cover is supported in the bottom support by the second supports.

7. The LCD device as claimed in claim 6 , wherein the bottom support includes at least one first support, and the inverter cover includes at least one first hook that is inserted into the at least one first support of the bottom support.

8. The LCD device as claimed in claim 7 , wherein the first hook is stepped to limit an insertion depth of the inverter cover.

9. The LCD device as claimed in claim 6 , wherein the bottom support includes at least one second support protruded in a thickness direction, and the inverter cover includes at least one second hook cut in a slit shape to be hooked in the second support of the bottom support and supported in a retreat direction.

10. The LCD device as claimed in claim 6 , wherein the second support is inclined from its start end to its end in an entry direction of the inverter cover.

11. The LCD device as claimed in claim 6 , wherein the bottom support includes a main support and a bottom cover.

12. A liquid crystal display (LCD) device, comprising:

an LCD panel to display images;

a backlight unit to supply light to the LCD panel;

a bottom cover provided with an inverter to supply an alternating current to the backlight unit, wherein the bottom cover includes first supports to support an inverter cover in a thickness direction, and second supports protruded between the first supports so that the first hooks of the inverter cover are inserted into the first supports and the second hook of the inverter cover is supported in the second support in a retreat direction by the second supports; and

wherein the inverter cover engaged with the bottom cover to receive the inverter.

13. The LCD device as claimed in claim 12 , wherein the inverter cover includes at least one hook to be supported in the bottom cover in a thickness direction, and at least one second support in a slit shape between the first hooks so that the inverter cover is hooked and supported in the bottom cover in a retreat direction.

14. The LCD device as claimed in claim 12 , wherein the bottom cover includes at least one first support, and the inverter cover includes at least one first hook inserted into the first support of the bottom cover to be supported in a thickness direction.

15. The LCD device as claimed in claim 14 , wherein the first hook is stepped to limit an insertion depth of the inverter cover.

16. The LCD device as claimed in claim 12 , wherein the bottom cover includes at least one second support protruded in a thickness direction, and the inverter cover is provided with at least one second hook cut in a slit shape to be hooked in the second support of the bottom cover and supported in a retreat direction.

17. The LCD device as claimed in claim 12 , wherein the second support is inclined from its start end to its end in an entry direction of the inverter cover.
