The first side frame is movable toward the first cabinet, and a portion of the first side frame extends to the first concave part. Thus, there may be provided a display device which may be independently used and also be used to constitute (or form) a tiling display device by connecting multiple display devices. ## Claims ### Claim 1 A display device comprising: a first display panel having a first main surface upon which an image is displayed, a second main surface opposite the first main surface, and a first side surface connecting the first main surface to the second main surface; a first housing disposed on a bottom of the first display panel; a first cabinet having a first side facing toward the first housing, a back side facing away from the first housing, and a side surface between the first side and the back side, the first cabinet disposed on a bottom of the first housing, the first cabinet including: a first protrusion part; and a first concave part that includes a connection part and a control part; and a first side frame disposed on the first side surface of the first display panel, a second display panel disposed adjacent to the first display panel; a second housing disposed on a bottom of the second display panel; a second cabinet having a first side facing toward the second housing, a back side facing away from the second housing, and a side surface between the first side and the back side, the second cabinet disposed on a bottom of the second housing, the second cabinet including a second protrusion part; at least one second protrusion part disposed on at least the side surface of the second cabinet, wherein the first side frame is movable toward the back side of the first cabinet, a portion of the first side frame extends to the first concave part, the connection part is connected to the first side frame and movable in a direction, the connection part includes an inclined surface corresponding to the second protrusion part, and the control part is fastened to the connection part to control movement of the connection part. ### Claim 2 (depends on 1) The display device of claim 1, further comprising: a second side frame disposed on the side surface of the second display panel, wherein the second display panel has a third main surface upon which an image is displayed, a fourth main surface opposite the first main surface, and a second side surface connecting the first main surface to the second main surface, the second cabinet includes a second concave part, the second side frame is movable toward the back side of the second cabinet, and a portion of the second side frame extends to the second concave part. ### Claim 3 (depends on 2) The display device of claim 2, wherein the first side frame covers the side surface of the first display panel and protects the first display panel, and the second side frame covers the side surface of the second display panel and protects the second display panel. ### Claim 4 (depends on 2) The display device of claim 2, wherein at least one first protrusion part and at least one first concave part are disposed on at least the side surface of the first cabinet, and at least one second concave part is disposed on at least the side surface of the second cabinet. ### Claim 5 (depends on 4) The display device of claim 4, wherein the control part includes a spring having elasticity. ### Claim 6 (depends on 5) The display device of claim 5, wherein the first protrusion part protrudes toward the second concave part, and the second protrusion part protrudes toward the first concave part. ### Claim 7 (depends on 6) The display device of claim 6, wherein in case that the first display panel and the second display panel are connected to each other, the first protrusion part is moved to an inside of the second concave part, and the second protrusion part is moved to an inside of the first concave part. ### Claim 8 (depends on 7) The display device of claim 7, wherein in case that the first display panel and the second display panel are connected to each other, the second protrusion part moves to the first concave part, contacts the inclined surface of the connection part, and applies a force to the control part such that the control part is moved in the direction. ### Claim 9 (depends on 8) The display device of claim 8, wherein in case that the first display panel and the second display panel are connected to each other, each of the first and second side frames is moved toward a corresponding one of the first and second cabinets. ### Claim 10 (depends on 1) The display device of claim 1, wherein a thickness of the second protrusion part is greater than that of the second side frame.
