Display device

1. A multi-display device, comprising:

a display module;

a frame positioned behind the display module;

a displacement adjustment unit positioned between the display module and the frame, mounted on the display module or the frame, and configured to adjust a distance between the display module and the frame; and

an attachment part fixed to the displacement adjustment unit and attached to or detached from the frame or the display module,

wherein the display module includes:

a first display module; and,

a second display module adjacent to the first display module,

wherein the displacement adjustment unit includes:

a first displacement adjustment unit installed at one of the first display module or the frame,

a second displacement adjustment unit installed at one of the second display module or the frame,

wherein the frame includes a mounting hole disposed at the other of the first display module or the frame,

wherein each of the first and second displacement adjustment unit is inserted into the mounting hole to adjust a difference of a height of the first display module and the second display module,

wherein the first displacement adjustment unit adjusts a first distance between the first display module and the frame, and

wherein the second displacement adjustment unit adjusts a second distance between the second display module and the frame,

wherein the attachment part includes:

a plurality of first magnetic parts; and,

a plurality of second magnetic parts having a polarity different from a polarity of the first magnetic part,

wherein the plurality of first and second magnetic parts are alternately arranged.

2. The multi-display device of claim 1 , wherein the first and second displacement adjustment units rotate in a first direction or a second direction opposite the first direction,

when the first displacement adjustment unit rotates in the first direction, the first distance is gradually longer,

when the first displacement adjustment unit rotates in the second direction, the first distance is gradually shortened,

when the second displacement adjustment unit rotates in the first direction, the second distance is gradually longer, and

when the second displacement adjustment unit rotates in the second direction, the second distance is gradually shortened.

3. The multi-display device of claim 1 , wherein the display module includes:

a display panel;

a module cover disposed behind the display panel; and,

a mounting part disposed in an inner space of the module cover,

wherein the displacement adjustment unit is partly inserted into the mounting part and mounted to the mounting part.

4. The multi-display device of claim 1 , wherein the displacement adjustment unit includes:

a head part;

a body extended from a lower surface of the head part; and,

an adjustment bar extended from one side of the head part,

wherein the plurality of first and second magnetic parts are alternately arranged on an upper surface of the adjustment bar.

5. The multi-display device of claim 4 , wherein the adjustment bar rotates in a first direction with respect to a center of the head part or in a second direction opposite the first direction,

when the adjustment bar rotates in the first direction, the distance is gradually longer,

when the adjustment bar rotates in the second direction, the distance is gradually shorten.
