wherein the 1-1th bar is rotatably connected to the 1-2th bar with respect to a first point between the fifth end and the seventh end, and the 1-3th bar is rotatably connected to the 1-4th bar with respect to a second point between the sixth end and the eighth end.

5. The electronic device of claim 1 , further comprising a second supporting bracket connected with the second cover part and the housing, the second support bracket configured to support the second display area.

6. The electronic device of claim 5 , further comprising a hinge structure rotatably connecting the second supporting bracket to the housing.

7. The electronic device of claim 6 , wherein the hinge structure includes,

a fixing part disposed on a first surface of the housing configured to face the second cover part and

a rotation bracket coupled with the second supporting bracket, and configured to rotate about the fixing part.

8. The electronic device of claim 6 , wherein the second supporting bracket includes:

a third support member connected with the second cover part, and including a ninth end and a tenth end opposite to the ninth end, and

a plurality of second bars connected with the hinge structure and the third support member,

wherein the hinge structure includes a first hinge structure connected with a first housing end of the housing, and a second hinge structure connected with a second housing end opposite to the first housing end,

wherein the plurality of second bars include:

a 2-1th bar rotatably connected to the ninth end, a 2-2th bar rotatably connected to the first hinge structure, a 2-3th bar rotatably connected to the tenth end, and a 2-4th bar rotatably connected to the second hinge structure, and

wherein the 2-1th bar is rotatably connected to the 2-2th bar with respect to a third point between the first housing end and the ninth end, and the 2-3th bar is rotatably connected to the 2-4th bar with respect to a fourth point between the second housing end and the tenth end.

9. The electronic device of claim 8 , wherein the second supporting bracket includes:

a guide member connected with the plurality of second bars at the third point and the fourth point,

a fourth support member configured to slide within the guide member and

a plurality of third bars disposed between the third support member and the fourth support member.

10. The electronic device of claim 1 , wherein at least a portion of the first display area is exposed as to be visible through the first cover part.

11. The electronic device of claim 1 , further comprising:

a spring structure providing an elastic force to the roller in a direction in which the display is inserted into the housing; and

a damping member connected with the roller to provide a braking force for reducing the elastic force provided by the spring structure.

12. The electronic device of claim 1 , wherein the roller includes a plurality of end areas including a plurality of protrusions, and a central area positioned between the plurality of end areas, the central area oriented as to face the display, and

wherein the electronic device further includes a stopper structure configured to contact the plurality of protrusions.

13. The electronic device of claim 12 , further comprising an input structure at least partially exposed to an exterior of the housing, and connected with the stopper structure,

wherein the input structure is configured to change a position of the stopper structure with respect to the plurality of protrusions based on a user input.

14. The electronic device of claim 1 , wherein the first cover part is detachable from the housing in a first direction, and

wherein the second cover part is detachable from the housing in a second direction different from the first direction.

15. The electronic device of claim 1 , wherein the display includes a third display area between the first display area and the second display area, and

wherein the roller includes a receiving groove for receiving the third display area of the display.
