a mount plate disposed at a rear of the frame,
wherein the plate comprises a fixing part protruding rearward from a rear surface of the plate, passing through the frame, and coupled to the mount plate, and
wherein the mount plate comprises a hole which is aligned with the fixing part, and through which a fastening member fastened to the fixing part passes.

4. The display device of claim 1 ,
wherein the pin comprises:
a plurality of first pins disposed adjacent to a first side of the frame; and
a plurality of second pins disposed adjacent to a second side of the frame.

5. The display device of claim 4 , wherein the frame comprises:
a first long side;
a second long side opposite to the first long side;
a first short side connected to the first long side and the second long side; and
a second short side opposite to the first short side,
wherein:
the plurality of first pins are adjacent to the first short side and spaced apart from each other along the first short side; and
the plurality of second pins are adjacent to the second short side and spaced apart from each other along the second short side.

6. The display device of claim 1 , further comprising a plurality of adhesive members disposed between the plate and the frame, and coupled to the plate and the frame,
wherein the frame further comprises a plurality of ribs protruding from the front surface of the frame toward the rear surface of the plate, and spaced apart from the plurality of adhesive members.

7. The display device of claim 1 , further comprising a plurality of adhesive members disposed between the display panel and the plate, and coupled to the display panel and the plate,
wherein the plate comprises:
a flat plate portion; and
a pressed portion disposed at a perimeter of the flat plate portion, and pressed rearward from a front surface of the flat plate portion,
wherein the plurality of adhesive members are coupled to a front surface of the pressed portion.

8. A display device comprising:
a display panel;
a plate disposed at a rear of the display panel, and coupled to the display panel;
a frame disposed at a rear of the plate;
a mount plate disposed at a rear of the frame; and
a back cover covering a rear side of the mount plate,
wherein the plate comprises a fixing part protruding rearward from a rear surface of the plate, passing through the frame, and coupled to the mount plate, and
wherein the frame comprises a coupling part protruding rearward from a rear surface of the frame, passing through the mount plate, and coupled to the back cover.

9. The display device of claim 8 , wherein the fixing part comprises a plurality of fixing parts arranged along a perimeter of the mount plate,
wherein the coupling part comprises a plurality of coupling parts arranged along the perimeter of the mount plate, and spaced apart from the plurality of fixing parts.

10. The display device of claim 8 , wherein the back cover comprises a rear coupling part which is aligned with the coupling part, and through which a fastening member fastened to the coupling part passes.

11. The display device of claim 10 , further comprising an end cover covering a rear side of the back cover, and coupled to the back cover,
wherein the end cover comprises a guide protrusion protruding from a front surface of the end cover toward the rear coupling part, and inserted into the rear coupling part.

12. The display device of claim 1 , further comprising:
