4. The display apparatus of claim 2 , wherein one end of the fixing member is exposed on a front side of the display module such that the fixing member is rotatable at a front of the display module, and

another end of the fixing member is exposed on a rear side of the display module such that the fixing member is rotatable at a rear of the display module.

5. The display apparatus of claim 1 , wherein the display module further comprises a ground gasket mounted on the substrate to be in contact with a ground pad of the substrate, and

at least a portion of the ground gasket is provided to be in contact with the reinforcement member through a ground hole formed in the holder.

6. The display apparatus of claim 5 , wherein the display module further comprises a ground sealing member provided between the holder and the reinforcement member, and

wherein the ground sealing member extends along a periphery of the ground hole.

7. The display apparatus of claim 1 , wherein the display module further comprises a first connector exposed on a rear side of the display module through a first connector hole formed in the holder, and

the circuit case further comprises a second connector exposed on a front side of the circuit case through a second connector hole formed in the circuit case, and the second connector being coupled to the first connector.

8. The display apparatus of claim 7 , wherein the holder further comprises:

a first waterproof rib provided to surround the first connector hole; and

a second waterproof rib provided inside of the first waterproof rib to surround the first connector hole.

9. The display apparatus of claim 8 , wherein the first waterproof rib comprises a first drain hole provided at a lower end of the first waterproof rib, and

wherein the second waterproof rib comprises a second drain hole provided at a lower end of the second waterproof rib.

10. The display apparatus of claim 9 , wherein the second drain hole are arranged to be spaced apart from the first drain hole in an upper-to-lower direction and in a left-to-right direction.

11. The display apparatus of claim 8 , wherein the display module further comprises a sealing member provided inside of the second waterproof rib,

wherein the sealing member is configured to seal a region between the second waterproof rib and the first connector hole,

wherein the sealing member is coupled to the holder or the circuit case.

12. The display apparatus of claim 11 , wherein the holder further comprises:

a third waterproof rib provided inside of the second waterproof rib to surround the first connector hole; and

a sealing groove formed between the second waterproof rib and the third waterproof rib,

wherein the sealing member is inserted into the sealing groove.

13. The display apparatus of claim 7 , wherein the holder is configured to block water from being introduced to a region inside the holder from a region of the holder other than the first connector hole.

14. The display apparatus of claim 1 , wherein the display module comprises a plurality of display modules, and

wherein the cabinet is provided to support the plurality of display modules.

15. The display apparatus of claim 14 , wherein the cabinet comprises a plurality of cabinets, and

wherein the plurality of cabinets are provided to be coupled to each other in a horizontal direction and a vertical direction.

16. A display apparatus comprising:

a display module comprising a reinforcement member, a first waterproof rib, and a second waterproof rib; and

a cabinet comprising a plurality of magnets,

wherein the plurality of magnets of the cabinet is magnetically coupled with the reinforcement member of the display module,

wherein a first drain hole is provided at a lower end of the first waterproof rib, and

wherein a second drain hole is provided at a lower end of the second waterproof rib.

17. The display apparatus of claim 16 , wherein the second drain hole are arranged to be spaced apart from the first drain hole in an upper-to-lower direction and in a left-to-right direction.

18. The display apparatus of claim 16 , wherein the display module further comprises a sealing member provided inside of the second waterproof rib,

wherein the sealing member is configured to seal a region between the second waterproof rib and the first connector hole.
