Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body that moves in a first direction with respect to the first body, and a flexible display that varies according to the movement of the second body. Either one of the first body and the second body has coupled thereto a plurality of spherical rolling balls arranged in the first direction, and the other one has formed therein rolling grooves, in the form of concave grooves having a constant cross-section, in the first direction to allow the rolling balls to move in contact with same. In embodiments of the present invention, the movement of the second body is facilitated by a point contact of the rolling balls and the rolling grooves, and external exposure of an element for slidable movement of the second body may be minimized.
