Abstract

A display device including a display panel having an active area to display an image, and an inactive area provided with a pattern disposed thereto to apply an electrical signal to the active area, a side cover having a peripheral frame disposed at an outer portion of the display panel to form a side portion exterior of the display device, and a support frame extended from the peripheral frame to be disposed at a rear of the display panel and supporting the display panel, and a black matrix disposed at a front of the inactive area to hide a pattern of the inactive area.

Claims

1. A display device, comprising:

a display panel having an active area to display an image, and an inactive area provided with a disposed pattern disposed thereto to apply an electrical signal to the active area;

a side cover having a peripheral frame disposed at an outer portion of the display panel to form a side portion exterior of the display device, and a support frame extended from the peripheral frame to be disposed at a rear of the display panel and supporting the display panel; and

a black matrix disposed at a front of the inactive area to hide a pattern of the inactive area.

2. The display device of claim 1, wherein the side cover comprises a heat conductor, and is formed in a rectangular shape.

3. The display device of claim 1, wherein the peripheral frame of the side cover is formed such that a front surface of the display panel is entirely exposed.

4. The display device of claim 1, wherein the peripheral frame of the side cover comprises a front surface peripheral frame disposed at a front of the black matrix to cover a portion of a front surface of the display panel.

5. The display device of claim 4, wherein a width of the black matrix is larger than a width of the front surface peripheral frame such that at least one portion of the black matrix is exposed.

6. The display device of claim 1, wherein the black matrix is disposed at a front surface of the display panel, while corresponding to a position at which the pattern is formed.

7. The display device of claim 1, further comprising

a protective member disposed at a front of the display panel to protect the display panel,

wherein the black matrix is disposed on at least one of a front or a rear of the protective member.

8. The display device of claim 7, wherein the protective member comprises a plurality of layers having different material properties, and

the black matrix is disposed in between the plurality of layers.

9. The display device of claim 1, wherein the peripheral frame of the side cover comprises a first portion extended from the support frame toward a front, and a second portion extended from the support frame toward a rear.

10. The display device of claim 9, further comprising

a rear cover disposed at a rear of the display panel, disposed to form a rear portion exterior of the display device,

wherein the first portion of the peripheral frame covers an outer side of a side surface of the display panel to prevent the side surface of the display panel from being exposed while the second portion of the peripheral frame covers an outer side of a side surface of the rear cover to prevent the side surface of the rear cover from being exposed.

11. The display device of claim 1, further comprising

a rear cover configured to support the support frame of the side cover and disposed to form a rear portion exterior of the display device.

12. The display device of claim 11, wherein the rear cover is attached to the support frame of the side cover by use of an adhesive member.

13. The display device of claim 11, wherein the rear cover comprises a tempered glass.

14. The display device of claim 11, further comprising:

a middle panel disposed in between the display panel and the rear cover to reinforce the display panel.

15. The display device of claim 14, wherein the middle panel performs heat emission.

16. The display device of claim 14, wherein the middle panel is attached to a rear surface of the display panel by use of an adhesive member.

17. The display device of claim 14, further comprising:

a bracket panel disposed in between the display panel and the rear cover,

wherein the bracket panel comprises a first panel coupling portion disposed at an outer side of a side surface of the middle panel and attached to the display panel to reinforce the display panel, and a second panel coupling portion disposed in between the middle panel and the rear cover to be attached to the middle panel.

18. The display device of claim 17, wherein a part of the first panel coupling portion is disposed in between the display panel and the support frame of the side cover and coupled to the support frame of the side cover.

19. The display device of claim 17, further comprising:

a circuit board, disposed at a rear of the display panel, and electrically connected to the display panel,

wherein a space is formed in between a part of the first panel coupling portion and the rear cover, while the circuit board is disposed in the space.

20. A display device, comprising:

a display panel having an active area to display an image, and an inactive area provided with a pattern disposed thereto to apply an electrical signal to the active area;

a rear cover disposed at a rear of the display panel to form a rear portion exterior of the display device;

a side cover having a peripheral frame disposed at outer portions of the display panel and the rear cover to form a side portion exterior of the display device, and a support frame extended from the peripheral frame to be disposed between the display panel and the rear cover, and

a black matrix disposed at a front of the inactive area to hide a pattern of the inactive area.

21. The display device of claim 20, wherein the display panel is directly attached to a front surface of the support frame of the side cover by use of an adhesive member.

22. The display device of claim 20, wherein the display panel is supported by the support frame of the side cover by at least one medium.
