Abstract

Provided is a display device which may include a display panel having a long side in a first direction, a short side in a second direction, and a thickness in a third direction, a back cabinet disposed in the rear of the display panel, and a case that covers an edge of a front surface of the display panel. The case may include a horizontal case that covers an edge of the front surface of the display panel on a long side of the display panel and a vertical case covering an edge of the front surface of the display panel on a short side of the display panel. The horizontal case and the vertical case may be coupled to each other in a region corresponding to a corner of the display panel, and the horizontal case and the vertical case may be formed of different materials.

First claim

What is claimed is:

1. A display device comprising:
a display panel having a long side in a first direction, a short side in a second direction, and a thickness in a third direction;
a back cabinet disposed at a rear of the display panel; and
a case that covers an edge of a front surface of the display panel,
wherein the case includes a horizontal case that covers an edge of the front surface of the display panel on the long side of the display panel and a vertical case that covers an edge of the front surface of the display panel on the short side of the display panel,
wherein the horizontal case and the vertical case are coupled to each other in a region corresponding to a corner of the display panel,
wherein the horizontal case includes:
a first part extended in the second direction the first part including a portion covering the edge of the front surface of the display panel on the long side of the display panel;
a second part extended from a first end of the first part, the second part including a portion provided over a side of the display panel on the long side of the display panel; and
a third part extended from an end of the second part in the second direction, and

wherein the vertical case includes:
a first part extended in the first direction, the first part of the vertical case including a portion that covers the edge of the front surface of the display panel on the short side of the display panel;
a second part extended from the first part of the vertical case, the second part of the vertical case including a portion positioned near a side of the display panel on the short side of the display panel; and
a protrusion extended from the second part of the vertical case in the first direction and coupled to the horizontal case.

2. The display device of claim 1 , wherein the first part and the third part of the horizontal case are parallel to the display panel.

3. The display device of claim 1 , wherein the horizontal case further includes:
a fourth part that extends from a second end opposite the first end of the first part in the third direction and is provided over the front surface of the display panel on the long side of the display panel; and
a fifth part that extends from the fourth part in the second direction and configured to couple to the first part of the vertical case.

4. The display device of claim 3 , wherein the horizontal case further includes a sixth part that extends from the third part in the third direction,
wherein the sixth part of the horizontal case has a first hole to accommodate a fastening member.

5. The display device of claim 4 , wherein the protrusion includes a connection part that extends in the third direction and has a second hole corresponding to the first hole on the horizontal case.

6. The display device of claim 5 , further comprising a back cover provided between the back cabinet and the display panel,
wherein the back cabinet is coupled to the back cover.

7. The display device of claim 6 , wherein at least one of the horizontal case and the vertical case extends further than the back cabinet in the first or second directions.

8. The display device of claim 5 , wherein the third part of the horizontal case is separated from the back cabinet by a predetermined distance in the third direction.

9. The display device of claim 1 , wherein paint or tape is provided on a surface of at least one of the first part or the second part of the vertical case.

10. The display device of claim 1 , wherein the vertical case further includes an extension extended from the second part of the vertical case in the second direction,
wherein the protrusion extends from the extension in the first direction.

11. The display device of claim 10 , wherein the extension of the vertical case is positioned adjacent to an end of the horizontal case.

12. The display device of claim 10 , wherein the extension of the vertical case covers an end of the horizontal case.

13. The display device of claim 10 , wherein the first part of the horizontal case includes a first end and a second end, and
wherein the distance between the first end and the second end of the horizontal case in the second direction is different from the height of the extension of the vertical case.

14. The display device of claim 3 , wherein the protrusion of the vertical case is inserted into the horizontal case.

15. The display device of claim 3 , wherein the protrusion of the vertical case includes a hole,
wherein the horizontal case and the protrusion of the vertical case are coupled by a fastening member passing through the hole of the protrusion.

16. The display device of claim 3 , wherein the display device further comprises:
a back cover between the display panel and the back cabinet; and
a guide panel between the display panel and the back cover,
wherein a back surface of the display panel is supported by the guide panel.

17. The display device of claim 16 , wherein a part of the guide panel is attached to the back surface of the display panel through an adhesive layer.

18. The display device of claim 16 , wherein the display device further comprises:
a light guide panel between the display panel and the back cover; and
a optical layer between the display panel and the light guide panel.

19. The display device of claim 16 , wherein the case is coupled to a part of the back cover by a fastening member.

20. The display device of claim 16 , wherein the case covers a side of the guide panel on the side of the display device.

21. The display device of claim 3 , wherein the back cabinet covers at least a portion of the third part of the horizontal case.

22. The display device of claim 3 , wherein the back cabinet has a hole, and the back cabinet is coupled to the back cover by a fastening member passing through the hole.

23. The display device of claim 3 , wherein an end of the protrusion is further extended than the first part of the vertical case in the first direction.

24. A display device comprising:
a display panel;
a back cover disposed behind the display panel; and
a front cover provided over a front of the display panel to cover an edge around a circumference of the display panel,
wherein the front cover includes a horizontal portion to cover an edge along a width of the display panel and a vertical portion to cover an edge along a height of the display panel, the horizontal portion and the vertical portion having prescribed shapes to couple to each other,
wherein the horizontal portion includes:
