Other various embodiments are also possible. ## Claims ### Claim 1 An electronic apparatus comprising: a flexible display; a frame part configured to support the flexible display; and a rear cover coupled to an outer surface of the frame part to cover at least a portion of the frame part, wherein the rear cover is configured to be decoupled from the frame part based on an electrical signal. ### Claim 2 (depends on 1) The electronic apparatus of claim 1, wherein the frame part comprises: a first frame; and a second frame configured to slidably move relative to the first frame in response to a change in shape of the flexible display, wherein the rear cover is coupled to an outer surface of the second frame. ### Claim 3 (depends on 1) The electronic apparatus of claim 1, further comprising: a first element having two end portions fixed to the frame part and configured to be extended or contracted based on the electrical signal; a second element coupled to the first element and configured to move in a first direction in accordance with a contraction of the first element; and a third element having two end portions fixed to the frame part, pressurized in accordance with the contraction of the first element, and configured to cause the second element to move in a second direction opposite the first direction when the first element is extended. ### Claim 4 (depends on 3) The electronic apparatus of claim 3, wherein the rear cover comprises a hook on one surface thereof facing the frame part, and wherein the second element is further configured to be: in a state in which the second element is moved in the second direction and engaged with the hook to couple the rear cover to the frame part; or in a state in which the second element is moved in the first direction and disengaged from the hook to decouple the rear cover from the frame part. ### Claim 5 (depends on 3) The electronic apparatus of claim 3, wherein the first element is: contracted in response to the electrical signal being received; and extended in response to the electrical signal being released. ### Claim 6 (depends on 3) The electronic apparatus of claim 3, wherein the frame part comprises a guide rail configured to guide a path along which the second element moves in the first direction or the second direction. ### Claim 7 (depends on 1) The electronic apparatus of claim 1, wherein at least a portion of the flexible display is located between the frame part and the rear cover. ### Claim 8 (depends on 1) The electronic apparatus of claim 1, wherein at least a portion of the rear cover includes a substantially transparent material such that an image displayed on the flexible display is viewable through the rear cover. ### Claim 9 An electronic apparatus comprising: a flexible display comprising: a first area configured to display an image on a front side of the electronic apparatus; a second area configured to display an image on a rear side of the electronic apparatus; and a third area positioned between the first area and the second area, wherein a position of the third area is changeable; a frame part comprising a first frame supporting at least a portion of the first area and a second frame supporting the second area; and a rear cover coupled to the second frame on the rear side of the electronic apparatus, and configured to be decoupled from the second frame based on an electrical signal. ### Claim 10 An electronic apparatus comprising: a flexible display comprising: a first area configured to display an image on a front side of the electronic apparatus; a second area configured to display an image on a rear side of the electronic apparatus; and a third area positioned between the first area and the second area, a position of the third area being changeable; a frame configured to cover the third area of the flexible display; and at least one structure located between the flexible display and the frame and configured to block an inflow of an external material. ### Claim 11 (depends on 10) The electronic apparatus of claim 10, wherein the at least one structure comprises: a first structure having one end fixed to the frame and another end extending toward the first area such that a foreign substance entering between the first area and the frame is blocked. ### Claim 12 (depends on 11) The electronic apparatus of claim 11, wherein the first structure has at least one of an undercut shape or a protruding shape at an inner side surface facing the flexible display. ### Claim 13 (depends on 10) The electronic apparatus of claim 10, wherein the at least one structure comprises: a second structure disposed between the second area and the frame, facing the flexible display in a tangential direction of the flexible display and configured to prevent an external material entering between the third area and the frame from moving to the second area. ### Claim 14 (depends on 13) The electronic apparatus of claim 13, further comprising: an outlet through which the external material entering between the third area and the frame is discharged to outside; and a frame cover disposed to cover the outlet and detachably attached to the frame. ### Claim 15 (depends on 14) The electronic apparatus of claim 14, wherein the second structure has a shape of a roller and configured to: absorb the external material entering between the third area and the frame; and cause a foreign substance entering between the first area and the frame to move to the outlet.
