Abstract

There is provided a display device in which a drain hole is provided in incised portion of a middle cabinet supporting a display panel and a back cover, and thus plural circuit films and a printed circuit board and the like that are arranged in a circuit section coupled to the display panel can be protected by preventing inflow of moisture from the outside despite considerable reduction of a width of a front rim.

First claim

What is claimed is:

1. A display device comprising: a display panel; a middle cabinet including a first supporting portion and a second supporting portion that are substantially perpendicular to each other, wherein the second supporting portion protrudes from the first supporting portion and is configured to support the display panel by a front surface of the second supporting portion, the second supporting portion having one or two corner incisions; and a back cover that is directly coupled to a rear surface of the second supporting portion and has at least one drain hole, to drain moisture, formed at a bottom left corner or bottom right corner of the back cover to correspond to the one or two corner incisions of the middle cabinet.

2. The display device according to claim 1 , wherein a bottom left or bottom right corner of the middle cabinet in which a bottom part of the second supporting portion is coupled to a side part of the second supporting portion is incised in the middle cabinet.

3. The display device according to claim 2 , wherein the middle cabinet has a first step portion that is formed by incising an inner end of the second supporting portion in a direction of the first supporting portion.

4. The display device according to claim 3 , wherein the middle cabinet further has a second step portion that is formed by further incising an end of the first step portion in the direction of the first supporting portion and is closer to the bottom left or bottom right corner compared to the first step portion.

5. The display device according to claim 4 , wherein the second step portion corresponds to the at least one drain hole of the back cover.

6. The display device according to claim 4 , wherein the middle cabinet has an incision hole that is formed by further incising a bottom left or bottom right corner portion in which a bottom portion of the second step portion of the second supporting portion is coupled to a side portion of the second step portion of the second supporting portion to expose an inner surface of the first supporting portion.

7. The display device according to claim 6 , further comprising an absorption member provided between a top side surface of the second step portion and a bottom side surface of the display panel.

8. The display device according to claim 7 , wherein the absorption member is curved with wrapping the second step portion and is provided to wrap a rear surface of the back cover via the incision hole of the middle cabinet.

9. A display device comprising: a display panel; a middle cabinet including: a first supporting portion wrapping a side of an end of the display panel; and a second supporting portion comprising a front surface on which the display panel is mounted, the second supporting portion protruding inside from an inner surface of the first supporting portion and including one or two corner incisions; and a back cover directly coupled to a rear surface of the second supporting portion, and including at least one drain hole, to drain moisture, formed at a bottom left corner or bottom right corner of the back cover to correspond to the one or two corner incisions of the middle cabinet.

10. The display device of claim 9 , wherein the second supporting portion includes a first step portion that is formed by incising an inner end of the second supporting portion in a direction of the first supporting portion.

11. The display device of claim 10 , wherein the second supporting portion further includes a second step portion that is formed by further incising an end of the first step portion in the direction of the first supporting portion and is closer to the bottom left or bottom right corner compared to the first step portion.

12. The display device of claim 11 , wherein the second step portion corresponds to the at least one drain hole of the back cover.

13. The display device of claim 11 , wherein the middle cabinet further includes an incision hole that is formed by further incising a bottom left or bottom right corner portion in which a bottom portion of the second step portion is coupled to a side portion of the second step portion to expose an inner surface of the first supporting portion.

14. The display device of claim 11 further comprising an absorption member provided between a top side surface of the second step portion and a bottom side surface of the display panel.

15. The display device of claim 14 , wherein the absorption member is provided to wrap a rear surface of the back cover via the incision hole of the middle cabinet.

16. A narrow bezel display device comprising: a display panel; a middle cabinet including a first supporting portion and a second supporting portion configured to support the display panel by a front surface of the second supporting portion, the second supporting portion protruding from the first supporting portion and having at least one corner incision; and a back cover directly coupled to a rear surface of the second supporting portion, the back cover including at least one drain hole, wherein the middle cabinet further includes an incision hole at a bottom left corner or bottom right corner of the middle cabinet to drain moisture to the at least one drain hole of the back cover.

17. The narrow bezel display device according to claim 16 , wherein the bottom left or bottom right corner of the middle cabinet in which a bottom part of the second supporting portion is coupled to a side part of the second supporting portion is incised in the middle cabinet.

18. The narrow bezel display device according to claim 17 , wherein the middle cabinet has a first step portion that is formed by incising an inner end of the second supporting portion in a direction of the first supporting portion.

19. The narrow bezel display device according to claim 18 , wherein the middle cabinet further has a second step portion that is formed by further incising an end of the first step portion in the direction of the first supporting portion and is closer to the bottom left or bottom right corner compared to the first step portion.

20. The narrow bezel display device according to claim 19 , wherein the second step portion corresponds to the at least one drain hole of the back cover.
