5. The display device of claim 1 ,

wherein the connecter comprises:

a first body connected with the connection portion and the arm, the first body opened up and down; and

a first fastening member which penetrate the opening of the first body, and to which the first body is rotatably coupled to the arm, the first fastening member providing the first swivel axis.

6. The display device of claim 5 , wherein connector further comprises:

a fixing washer which is adjacent to one end of the first fastening member, which is fixed to an inner side of the arm, and through which the first fastening member passes;

a disc spring which is opposite to the one end of the first fastening member with respect to the fixing washer, which is convex toward the fixing washer, and through which the first fastening member passes;

a washer which is opposite to the fixing washer with respect to the disc spring, and through which the first fastening member passes; and

a bushing which is opposite to the disc spring with respect to the washer, and through which the first fastening member passes, the bushing including a flange positioned on the first body and a portion positioned in the opening of the first body.

7. The display device of claim 1 , wherein the elevating module comprises a rotation unit rotating about a second swivel axis extending in a vertical direction,

wherein the rotation unit comprises:

a vertical member coupled to the pole;

a second body connected to the vertical member and opened up and down; and

a second fastening member which penetrates the opening of the second body, to which the second body is rotatably coupled, and which is fixed to the arm, the second fastening member providing the second swivel axis.

8. The display device of claim 1 , wherein the elevating module comprises:

a vertical member positioned inside the pole, extending in the length direction of the pole, and coupled to the arm; and

a stem positioned between the vertical member and the base, coupled to the base.

9. The display device of claim 8 , wherein the elevating module further comprise a roller coupled to one side of the vertical member such that the roller is supported by an inner surface of the pole when the vertical member moves in the length direction of the pole.

10. The display device of claim 8 , further comprising the cable extending along the pole,

wherein the cable is inserted into the vertical member and the stem such that the cable is arranged in the pole.

11. The display device of claim 10 , wherein the connector comprises an elastic member which is wound around an outer circumference of the tilt shaft in a coil shape, and which includes one end in contact with the rear bracket and the other end in contact with the holder.

12. The display device of claim 10 , wherein the arm comprises a cable groove formed onto a lower surface of the arm, the cable groove extended from the connector toward the elevating module, and
