Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body, a roller, and a flexible display. The flexible display includes a first region forming a plane surface and a second region of which a portion forms a curved surface around the roller. A plurality of engagement protrusions are formed on an outer circumferential surface of the roller, and a plurality of support bars are coupled to an inner surface of the second region. The engagement protrusions engage the support bars. When the second body moves relative to the first body, the roller rotates with the engagement protrusions engaging the support bars, and the second region is uniformly deformed and moves.
