Display device

1 . A display device comprising:

a frame; and

a plurality of display modules coupled to the frame, wherein each of the plurality of display modules includes:

a display panel having a first surface and a second surface opposite to the first surface, including:

a substrate having a side surface;

a side line on the side surface of the substrate; and

a protection layer having a side surface, wherein the protection layer covers at least a portion of the side line; and

a cover film disposed on the first surface of the display panel,

wherein the plurality of display modules are spaced apart from each other on the frame,

wherein each of the plurality of display modules includes a bottom cover disposed on the second surface of the display panel,

wherein the bottom cover includes a plurality of protrusions extending toward the frame and the plurality of protrusions include fastener holes, and

wherein fasteners are configured to couple to the fastener holes to fix the plurality of protrusions to the frame.

2 . The display device of claim 1 , wherein a first separation distance between sides surfaces of the protection layers and a second separation distance between side surfaces of the cover films of the plurality of display modules on the frame are the same, and

wherein a third separation distance between side surfaces of the bottom covers of the plurality of display modules is greater than the first separation distance between side surfaces of the protection layers.

3 . The display device of claim 2 , wherein the bottom cover does not overlap the protection layer.

4 . The display device of claim 2 , wherein the frame includes a plurality of insertion holes into which the plurality of protrusions are inserted.

5 . The display device of claim 4 , wherein the protrusion is a portion of the bottom cover.

6 . The display device of claim 4 , further comprising a resin filling the insertion hole to fix the protrusion.

7 . The display device of claim 6 , wherein the frame includes a plurality of sub-frames and fixing pins configured to couple the plurality of sub-frames together, and

the plurality of sub-frames are coupled one-to-one to the plurality of display modules.

8 . The display device of claim 1 , wherein the plurality of display modules each include a plurality of electrode pads disposed at edges thereof and electrically connected to the side lines, and

wherein shapes of the plurality of electrode pads disposed on facing side surfaces of neighboring display modules of the plurality of display modules are different.

9 . The display device of claim 1 , wherein the plurality of display modules include a plurality of electrode pads disposed at edges thereof and electrically connected to the side lines, and

wherein shapes of the plurality of electrode pads disposed on facing side surfaces of neighboring display modules of the plurality of display modules are the same.

10 . The display device of claim 1 , wherein the plurality of display modules include a plurality of micro light emitting diodes.

11 . A display device, comprising:

a frame;

a plurality of display modules coupleable to the frame, each of the plurality of display modules including:

a display panel having a first surface and a second surface;

a bottom cover disposed on the second surface of the display panel; and

a plurality of fasteners configured to fix the plurality of display modules to the frame, with the plurality of display modules spaced apart from each other on the frame,

wherein each of the plurality of fasteners includes a first nut inserted into an opening hole in one of the plurality of display modules, a second nut disposed inside the first nut, and a bolt coupled to the second nut, and

wherein the second nut is configured to move upward when the bolt rotates, and the bolt is configured to move downward in response to the upward movement of the second nut being blocked by the frame.

12 . A display device, comprising:

a frame;

a plurality of display modules coupleable to the frame, each of the plurality of display modules including:

a display panel having a first surface and a second surface;

a bottom cover disposed on the second surface of the display panel, and a plurality of fasteners configured to fix the plurality of display modules to the frame, wherein the plurality of display modules are spaced apart from each other on the frame,

wherein each of the plurality of fasteners includes a nut disposed in a groove formed in one of the plurality of display modules, and a bolt coupled to the nut, and

an adhesive between the nut and the groove to couple the nut to the groove.

13 . The display device of claim 12 , wherein the adhesive member is an ultraviolet curable resin, and

the bolt and the nut include a material which transmits ultraviolet light.
