Abstract

A display device including a display panel having a back surface and a front surface; a side frame extending along three sides of the display panel and including a flat portion facing a part of the back surface of the display panel and an inclined portion extended rearward away from the flat portion and being exposed outside of the display device; a main frame comprising a plate and being coupled with the side frame; a light source between the display panel and the main frame. Further, the part of the back surface of the display panel is fixed on the flat portion of the side frame via an adhesive layer formed on the flat portion of the side frame. In addition, the side frame further includes an outer frame forming an outer perimeter of the side frame; an inner frame positioned inside the outer frame; and a stepped portion formed by the inner frame and the outer frame and configured to seat the main frame.

First claim

What is claimed is:

1. A display device comprising:
a display panel having a back surface and a front surface;
a side frame extending along a side of the display panel and including a flat portion facing a part of the back surface of the display panel and an inclined portion extended rearward away from the flat portion and being exposed outside of the display device;
a main frame comprising a plate and being coupled with the side frame; and
a light source between the display panel and the main frame,
wherein the part of the back surface of the display panel is fixed on the flat portion of the side frame.

2. The display device of claim 1 , wherein the inclined portion of the side frame is an exterior surface of the display device.

3. The display device of claim 1 , further comprising an adhesive member attached on the flat portion,
wherein the display panel is attached on the adhesive member.

4. The display device of claim 1 , wherein the side frame includes a first part along a short side of the display panel and a second part bent from the first part of the side frame along a long side of the display panel, and
wherein a gap is formed between the first part and the second part of the side frame.

5. The display device of claim 4 , wherein the gap is formed between the flat portion of the first part of the side frame and the flat portion of the second part of the side frame.

6. The display device of claim 4 , wherein the side frame comprises metal materials.

7. The display device of claim 1 , wherein the side frame further includes a first part along a first short side of the display panel, a second part bent from the first part of the side frame along a first long side of the display panel and a third part bent from the second part of the side frame along a second short side of the display panel opposite the first short side of the display panel, and
wherein a first gap is formed between the first part and the second part of the side frame, and a second gap is formed between the second part and the third part of the side frame.

8. The display device of claim 7 , further comprising a bottom frame being coupled with the first part and the third part of the side frame, the bottom frame positioned along a second long side of the display panel opposite the first long side of the display panel.

9. The display device of claim 1 , wherein the side frame includes a coupling protrusion, a space or a gap is formed between a portion of the side frame and the coupling protrusion, and the space or the gap is behind the display panel, and
wherein an end of the main frame is inserted into the space or the gap.

10. The display device of claim 1 , wherein the side frame includes:
an outer frame forming an outer perimeter of the side frame;
an inner frame positioned inside the outer frame; and
a stepped portion being formed by the inner frame and the outer frame.

11. The display device of claim 10 , wherein the outer frame is backwardly inclined.

12. The display device of claim 10 , wherein the outer frame includes a guide protrusion protruding along an extension direction of the outer frame toward an inside of the side frame, and
wherein the main frame includes a guide groove extending along a side of the main frame and is coupled with the side frame.

13. The display device of claim 10 , wherein the outer frame includes a coupling protrusion protruding from a back surface of the outer frame to an inside of the side frame and extending along a longitudinal direction of the outer frame, and
wherein the main frame slides on the side frame and is fixed to the side frame through the coupling protrusion.

14. The display device of claim 10 , further comprising:
an optical member between the main frame and the display panel,
wherein the inner frame includes a groove at its back surface,
wherein the optical member has a coupling portion which is positioned inside the inner frame and protrudes to the outside of the optical member, and
wherein the coupling portion of the optical member is inserted into the groove of the inner frame.

15. The display device of claim 14 , wherein the inner frame includes a hanging portion protruding from the groove of the inner frame and inserted into the coupling portion.

16. The display device of claim 1 , wherein the side frame bends and is positioned on at least two sides of the main frame, and
wherein the side frame further includes a gap near a corner of the side frame.

17. The display device of claim 16 , wherein the gap is positioned apart from the corner of the side frame.

18. The display device of claim 1 , wherein a front edge of the display panel is exposed in front of the display device.

19. The display device of claim 1 , wherein the main frame has a rectangular plate shape,
wherein the side frame is positioned on three sides of the main frame, and
wherein the display device further comprises a bottom frame positioned on a remaining side of the main frame and coupled with the side frame.

20. The display device of claim 19 , further comprising:
a wire electrically connected to the display panel, extended from one side of the display panel, and passing between the main frame and the bottom frame.

21. A display device comprising:
a display panel;
a side frame extended along a side of the display panel and positioned adjacent to an edge of the display panel, wherein the side frame comprises a flat portion facing a part of the back surface of the display panel, and an inclined portion extended rearward from the flat portion;
a main frame being a plate and coupled with the side frame;
a light source between the display panel and the main frame; and
an adhesive member attached on the flat portion,
wherein the part of the back surface of the display panel is attached on the adhesive member,
wherein the inclined portion of the side frame is an exterior surface of the display device and a front edge of the display panel is exposed in front of the display device,
wherein the side frame includes a first part along a short side of the display panel and a second part bent from the first part of the side frame along a long side of the display panel, and
wherein a gap is formed between the first part and the second part of the side frame.
