An electronic device is provided. The electronic device includes a first housing, a second housing coupled to an edge of the first housing and configured to rotate about a folding axis extending in a first direction, a third housing coupled to the first housing and disposed to be slidable toward or away from the folding axis, and a flexible display including a first area disposed on the third housing and a second area extending from the first area and disposed through the first housing to the second housing. As the third housing slides, the second area may slide on the first housing or the second housing, and a portion of the second area may be selectively received in the second housing.
