a main frame 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 inner frame of the side frame,
wherein the side frame includes a coupling protrusion, and
wherein the main frame is inserted into a space formed by the coupling protrusion of the side frame.

2. The display device of claim 1 , wherein the coupling protrusion protrudes toward an inside of the side frame.

3. The display device of claim 1 , wherein the inner frame includes a flat portion facing the part of the back surface of the display panel, and the part of the display panel sits on the flat portion.

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

5. The display device of claim 3 , 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 cut-out is formed between the first part and the second part of the side frame.

6. The display device of claim 5 , wherein the cut-out 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.

7. The display device of claim 1 , wherein the inclined surface of the outer frame is backwardly inclined.

8. The display device of claim 1 , wherein the side frame 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 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 the first part, the second part and the third part of the side frame respectively includes the inclined surface.

9. 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 cut-out is formed between the first part and the second part of the side frame, and a second cut-out is formed between the second part and the third part of the side frame.

10. The display device of claim 9 , 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.

11. The display device of claim 1 , wherein the side frame comprises metal materials.

12. The display device of claim 1 , wherein the outer frame forms an outer perimeter of the side frame, the inner frame is positioned inside the outer frame, and a stepped portion is formed by the inner frame and the outer frame, and
wherein the main frame sits on the stepped portion.

13. The display device of claim 1 , wherein the coupling protrusion includes a guide protrusion protruding along an extension direction of the side frame at a rear of the side frame,
wherein the main frame includes a guide groove extending along a side of the main frame, and
wherein the guide protrusion is inserted into the guide groove.

14. The display device of claim 1 , wherein the coupling protrusion protrudes along an extension direction of the side frame at a rear of the side frame.

15. The display device of claim 1 , further comprising:
an optical member between the main frame and the display panel,
wherein the side frame includes a groove at its back surface,
wherein the optical member has a coupling portion which protrudes toward an outside of the optical member, and
wherein the coupling portion of the optical member is inserted into the groove of the side frame.

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

17. 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 cut-out near a corner of the side frame.

18. The display device of claim 17 , wherein the cut-out is positioned apart from the corner of the side frame.

19. The display device of claim 1 , wherein a front surface at an edge of the display panel is exposed in front of the display device.

20. 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.

21. The display device of claim 20 , 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.

22. 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 an inner frame facing a part of the back surface of the display panel, and an exterior frame extended from the inner frame, wherein the exterior frame includes an exterior inclined portion,
