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 at least two sides of the display panel,
wherein the case includes a horizontal case that covers a side of the display panel on the long side of the display panel and a vertical case that covers a side 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 horizontal side part extended in the third direction, the horizontal side part including a portion covering the side of the display panel on the long side of the display panel; and
a horizontal back part extended from an end of the horizontal side part in the second direction,

wherein the vertical case includes:
a vertical side part extended in the third direction, the vertical side part of the vertical case including a portion that covers the side of the display panel on the short side of the display panel;
a vertical back part extended from an end of the vertical side part of the vertical case in the first direction, and
a protrusion extended from the vertical side part of the vertical case in the first direction and coupled to the horizontal case.

2. The display device of claim 1 , wherein the horizontal case further includes a first hole to accommodate a fastening member and the first hole is positioned adjacent to the protrusion of the vertical case.

3. The display device of claim 2 , 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.

4. The display device of claim 3 , wherein the display device further comprises a back cover provided between the back cabinet and the display panel,
wherein the back cabinet is coupled to the back cover.

5. The display device of claim 4 , wherein at least one of the horizontal case and the vertical case extends further than the back cabinet in the first or second directions.

6. The display device of claim 1 , wherein the horizontal back part of the horizontal case is separated from the back cabinet by a predetermined distance in the third direction.

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

8. The display device of claim 7 , wherein the extension of the vertical case is positioned adjacent to an end of the horizontal case.

9. The display device of claim 7 , wherein the extension of the vertical case covers an end of the horizontal case.

10. The display device of claim 1 , wherein the protrusion of the vertical case is inserted into the horizontal case.

11. The display device of claim 1 , 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.

12. The display device of claim 11 , wherein a part of the guide panel is attached to the back surface of the display panel through an adhesive layer.

13. The display device of claim 11 , 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.

14. The display device of claim 11 , wherein the case is coupled to a part of the back cover by a fastening member.

15. The display device of claim 1 , wherein the back cabinet covers at least a portion of the horizontal back part of the horizontal case or the vertical back part of the vertical case.

16. The display device of claim 11 , 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.

17. A display device comprising:
a display panel;
a back cover behind the display panel; and
a front cover provided around a circumference of the display panel,
wherein the front cover includes a horizontal portion to cover a side along a width of the display panel and a vertical portion to cover a side 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:
a lateral surface that extends along the width of the display panel to cover a side of the display panel, and
a rear surface that extends vertically from the lateral surface parallel to the back surface of the display panel,

wherein the vertical portion includes a protrusion extending horizontally from an end of the vertical portion into the horizontal portion, the protrusion having a hole, and
wherein the horizontal portion and the vertical portion are coupled each other through the hole.

18. The display device of claim 17 , wherein the horizontal portion includes a first hole provided on the horizontal portion to correspond to a second hole for the vertical portion of the front cover,
wherein the second hole is the hole of the protrusion.

19. The display device of claim 18 , wherein the first hole and the second hole are provided a prescribed distance horizontally from the vertical portion of the front cover.

20. The display device of claim 18 , wherein the vertical portion includes:
a back surface that extends horizontally behind the display panel to cover an edge along the height of the display panel, and
a lateral surface that extends forward from the back surface of the vertical portion to cover a side of the display panel,
wherein a height of the lateral surface of the vertical portion is greater than a height of the back surface of the vertical portion,
wherein the protrusion extends farther than the back surface of the vertical portion, and
wherein the second hole is provided on the protrusion to correspond to the first hole provided on the horizontal portion, the horizontal portion and the vertical portion of the front case being coupled using a fastener provided through the first and second holes.
