the monitor fitting of the first support member includes a pair of upper-side monitor fittings that are arranged at upper-side corner portions of the back surface of the display device, and a pair of lower-side monitor fittings that are arranged at lower-side corner portions of the back surface of the display device;

the pin member of the second support member includes a base end portion having a large diameter and provided on the fixing-side support plate, and a support pin having a small diameter and provided in a standing manner in the vertical direction on the base end portion;

a width dimension of a long hole of the upper-side monitor fitting is set so as to be engaged with the base end portion of the pin member, and a width dimension of a long hole of the lower-side monitor fitting is set so as to be engaged with the support pin of the pin member; and

in a case of the first support member being engaged with the second support member, the long hole of the upper-side monitor fitting is engaged with the base end portion of the pin member, the display-side support plate of the upper-side monitor fitting is supported by the fixing-side support plate of the second support member, and the long hole of the lower-side monitor fitting is arranged at a midway portion along a length direction of the support pin of the pin member.

2. The fixing structure of a multi-screen display device according to claim 1 , wherein:

the pin member of the second support member includes a pair of base end portions having a large diameter and provided spaced apart in the lateral direction on the fixing-side support plate, and support pins having a small diameter and provided in a standing manner in the vertical direction on each of the base end portions; and

in the case of at least two display devices being adjacently arranged in the lateral direction, the pin member on one side of the second support member is inserted in the long hole of the first support member that is provided in the display device on one side, and the pin member on an other side of the second support member is inserted in the long hole of the first support member that is provided in the display device on an other side.

3. The fixing structure of a multi-screen display device according to claim 1 , wherein a screw is provided in the display-side support plate of the first support member and the fixing-side support plate of the second support member, and mutually fastens the display-side support plate and the fixing-side support plate, in a state of the pin member being inserted in the long hole that is formed in the display-side support plate of the first support member.

4. The fixing structure of a multi-screen display device according to claim 1 , wherein:

the first support member comprises an L-shape fitting; and

a plate-like body on one side of the L-shape fitting includes a display-side support plate of an upper-side monitor fitting that has a large-diameter long hole whose width dimension is set so as to be engaged with the base end portion of the pin member, and a plate-like body on an other side of the L-shape fitting includes a display-side support plate of a lower-side monitor fitting that has a small-diameter long hole whose width dimension is set so as to be engaged with the support pin of the pin member.

5. A fixing method of a multi-screen display device that forms a large screen by adjacently arranging a plurality of display devices on a mounting seat, the method comprising:

arranging at corners of a back surface of a display device a monitor fitting that includes a display-side support plate that is provided so as to project out from the back surface of the display device and a long hole that is formed in the display-side support plate along with a lateral direction of the display device; and

adjusting misalignment in the lateral direction of the display device by inserting a pin member that is provided on the mounting seat via a fixing-side support plate in a long hole of the monitor fitting provided on the back surface of the display device, and by adjusting a position of the pin member with respect to the long hole along a lengthwise direction of the long hole.

6. The fixing method of a multi-screen display device according to claim 5 , comprising:

preparing, as the monitor fitting, a pair of upper-side monitor fittings that are arranged at upper-side corners of the back surface of the display device, and a pair of lower-side monitor fittings that are arranged at lower-side corners of the back surface of the display device; and

supporting display-side support plates of the upper-side monitor fittings with fixing-side support plates that are fixed to the mounting seat, in a state of pin members that are provided on the mounting seat via fixing-side support plates being inserted in long holes of the upper-side and lower-side monitor fittings.

7. The fixing method of a multi-screen display device according to claim 6 , comprising:

coupling the fixing-side support plate and the display-side support plate by screwing a screw into the fixing-side support plate that is fixed to the mounting seat and the display-side support plate of the upper-side monitor fitting that is supported by the fixing-side support plate.

8. The fixing method of a multi-screen display device according to claim 5 , comprising:

arranging a pair of pin members adjacently in a lateral direction on the mounting bracket at a location where at least two display devices are adjacently arranged in the lateral direction; and

inserting the pin member on one side in a long hole of a monitor fitting that is provided in the display device on one side, and inserting the pin member on an other side in a long hole of a monitor fitting that is provided in the display device on an other side.

9. The fixing method of a multi-screen display device according to claim 8 , comprising:

forming a support member by adjacently arranging the pair of pin members that the holes of the monitor fittings are inserted in; and

arranging a plurality of the support members in accordance with an installation interval of the long holes of the monitor fittings that are arranged along the lateral direction of the display device.
