Abstract

A display device includes a liquid crystal module to display an image at a front surface thereof, a cover to encase at least a portion of the liquid crystal module, and at least one fastening unit to couple the cover to the liquid crystal module, wherein the fastening unit is provided at a rear surface of the liquid crystal module.

Claims

1. A display device comprising:

a liquid crystal module which displays an image;

a cover which encases at least a portion of the liquid crystal module; and

at least one fastening unit which couples the cover to the liquid crystal module,

wherein the fastening unit is provided at a rear surface of the liquid crystal module.

2. The display device according to claim 1, wherein the fastening unit couples the cover and the rear surface of the liquid crystal module.

3. The display device according to claim 1, wherein the fastening unit couples the cover and the rear surface of the liquid crystal module with a screw type fastener.

4. The display device according to claim 3, wherein the fastening unit comprises a first fastening portion provided at the rear surface of the liquid crystal module, a second fastening portion provided at the cover, and a fastening screw coupled with the first fastening portion through the second fastening portion.

5. The display device according to claim 1, wherein the fastening unit couples the cover and the rear surface of the liquid crystal module in with a hook-type fastener.

6. The display device according to claim 5, wherein the fastening unit comprises a first fastening portion provided at the rear surface of the liquid crystal module and has a first hook structure, and a second fastening portion provided at the cover and has a second hook structure corresponding to the first hook structure.

7. The display device according to claim 1, wherein the cover comprises a first cover which encases a frame area of the rear surface of the liquid crystal module, and a second cover which encases a central area of the rear surface of the liquid crystal module.

8. The display device according to claim 7, wherein the first cover comprises a frame portion provided at a position adjacent to a frame of the rear surface of the liquid crystal module, and a side surface portion provided at a position adjacent to a side surface of the liquid crystal module.

9. The display device according to claim 8, wherein:

the side surface portion comprises a front end located adjacent to an edge of a front surface of the liquid crystal module, and a rear end located adjacent to an edge of the rear surface of the liquid crystal module; and

the front end is formed to have a smaller thickness than a thickness of the rear end.

10. The display device according to claim 7, wherein the first cover is made of a plastic material, whereas the second cover is made of a metal material.

11. The display device according to claim 7, wherein the first cover is formed with a mounting position guide portion to guide a mounting position of the second cover.

12. The display device according to claim 11, wherein the mounting position guide portion comprises a first mounting position guide portion which supports a base surface of the second cover, and a second mounting position guide portion which supports an upper surface of the second cover.

13. The display device according to claim 7, wherein the second cover is formed with a vent hole which passes air.

14. The display device according to claim 1, further comprising:

a bracket coupled to the rear surface of the liquid crystal module; and
