Abstract: A flexible display device is disclosed. The flexible display device comprises a first body, a second body, a flexible display, a ball module, and rails. The ball module includes a case and a plurality of moving balls. The moving balls are inserted into circulation paths of the case and arranged to be movable along the circulation paths, and some of the moving balls are in contact with sliding grooves of the rails. The case may be fixed to the first body, and the rails may be fixed to the second body. When the second body moves in parallel to a first direction with respect to the first body, the moving balls in contact with the sliding grooves roll and move along the circulation paths, such that slippage and friction generated on the ball module can be reduced, and the second body can move smoothly.
