1. An electronic device, comprising:
a flexible display including a first area and a second area extending from the first area;
a first structure configured to support the first area of the flexible display and slide relative to a second structure;
the second structure configured to guide a sliding of the first structure such that the second area of the flexible display is exposed to an outside of the second structure when the first structure is at an open position or is allowed to be received in the second structure when the first structure is at a closed position, wherein the first area of the flexible display is substantially flat shaped and exposed to the outside of the second structure when at the open and the closed positions;
a roller disposed in the second structure and configured to guide the second area of the flexible display to deform between a flat shape and curved shapes according to the sliding of the first structure; and
a support sheet configured to wind around the roller as the first structure is slid in to the closed position or unwind from the roller as the first structure is slid out to the open position for maintaining a first curvature and a second curvature substantially to a certain degree,
wherein the first curvature is a curvature of a curved shaped portion of the second area when the first structure is at the closed position and the second curvature is the curvature of a curved shaped portion of the second area when the first structure is at the open position, the first curvature being decreased compared to the second curvature, and
wherein a flat shaped portion of the second area is received in the second structure as the support sheet is wound around the roller.
