With the components described above, the display apparatus  1  may rotate clockwise or counter-clockwise with respect to an axis extending in a vertical direction. That is, the display apparatus  1  may be able to swivel. Naturally, it is necessary to provide the rotating pin  181  included in the upper portion of the base section  170  and the rotating pin  181  included in the lower portion thereof on the same vertical line. 
         [0100]    The top surface  183  of the rotating pin  181  may be in contact with the lubricating member  135  or the top surface  134  of the pin accommodating section  131  to support a load when there is no lubricating member  135 . 
         [0101]    The wall coupling unit  160  may further include the bearing members  190  which support an axial load and reduces abrasion. The bearing member  190  may be press-fitted or welded onto an outer circumferential surface  182  of the rotating pin  181 . A bottom of the bearing member  190  may be supported by a lip  184  of a lower portion of the rotating pin  181 . 
         [0102]    The bearing member  190  may be in contact with the bearing member  140  provided on the display apparatus coupling unit  110  which has been described above, may distribute a load, and may reduce abrasion caused by rotation. 
         [0103]    The wall coupling unit  160  may include a wire guide section which guides the wires  301  and  302  connected to the display apparatus  1 . 
         [0104]    The wire guide section includes a wire through hole  175  formed in the base section  170 . 
         [0105]    The wires  301  and  302  may sequentially pass through a wire through hole  33  of the reinforcing plate  30 , the wire through slit  24  of the rear cover  20 , the wire through hole  125  of the display apparatus coupling unit  110 , the wire path  111  formed between the display apparatus coupling unit  110  and the wall coupling unit  160 , and the wire through hole  175  of the wall coupling unit  160  and may electrically connect the circuit board  40  with external components. 
         [0106]      FIG. 11  is a view illustrating a mounting and separation structure of the display apparatus coupling unit  110  and the wall coupling unit  160  according to an exemplary embodiment.  FIG. 12  is a view illustrating a swivel operation of the display apparatus  1  according to an exemplary embodiment.  FIG. 13  is a view of a wire guide section of the wall mounting device  100  according to an exemplary embodiment. 
         [0107]    Referring to  FIGS. 11 to 13 , the installation and operation of the wall mounting device  100  will be described. 
         [0108]    As shown in  FIG. 11 , the display apparatus coupling unit  110  is fixedly coupled with the rear surface of the display apparatus  1 , the wall coupling unit  160  is fixedly coupled with the wall W, and the locking part  130  of the display apparatus coupling unit  110  is mounted on the supporting section  180  of the wall coupling unit  160 , thereby mounting the display apparatus  1  on the wall W. 
         [0109]    Here, the rotating pin  181  of the supporting section  180  is rotatably inserted into the pin accommodating section  131  of the locking part  130 . Accordingly, as shown in  FIG. 12 , the display apparatus  1  may be rotatable in a clockwise direction and a counter-clockwise direction with respect to a vertical axis. 
         [0110]    The display apparatus coupling unit  110  may be coupled with and supported by the wall coupling unit  160  while being mounted on the wall coupling unit  160  to allow the rotating pin  181  to be inserted in the pin accommodating section  131 . Alternatively, the display apparatus coupling unit  110  may be separated from the wall coupling unit  160  only by lifting the display apparatus  1  to disengage the rotating pin from the pin accommodating section  131 . 
         [0111]    As shown in  FIG. 13 , the wires  301  and  302  may pass through the wall mounting device  100  and may electrically connect the circuit board  40  inside the display apparatus  1  with external components. 
         [0112]    The wires  301  and  302  may be guided outward through the wire through hole  175  formed in a rear wall  175   a  of the wall coupling unit  160 . Accordingly, the wires  301  and  302  may be guided into the wall while being not exposed to the outside. 
         [0113]      FIG. 14  is a view of a wire guide section of the wall mounting device  100  according to an exemplary embodiment.  FIG. 15  is a cross-sectional view of a wall mounting device  200  according to still an exemplary embodiment. 
         [0114]    Hereinafter, a description of the same components as the described above will be omitted. 
         [0115]    As shown in  FIG. 14 , a wire through hole  177  may be formed in a sidewall  177   a  of the wall coupling unit  160 . With this structure, the wires  301  and  302  may be guided to the inside of the room instead of to the inside of a wall. 
         [0116]    As shown in  FIG. 15 , contrary to the above-described embodiment, a rotating pin  231  may be provided on a display apparatus coupling unit  210  of the wall mounting device  200  and a pin accommodating section  281  which rotatably accommodates the rotating pin  231  may be provided on a wall coupling unit  260 . 
         [0117]    As is apparent from the above description, the wall mounting device in accordance with an exemplary embodiment may have a smaller thickness. Accordingly, a display apparatus can be disposed to be attached closer to a wall, thereby providing an increase in availability of space and aesthetic. 
         [0118]    The swiveling of the display apparatus can be enabled by the support of wall mounting device. 
         [0119]    A neat and easy arrangement of the wires can be provided by the guiding of the wires connected to the display apparatus by the wall mounting device. 
         [0120]    Although exemplary embodiments have been particularly shown and described above, it would be appreciated by those skilled in the art that various changes may be made in these embodiments without departing from the principles and spirit of the inventive concept, the scope of which is defined by the following claims.
