Abstract: A flexible display device is provided. A flexible display device according to an embodiment of the present invention is configured to include a body, a moving plate, a flexible display, and a driving module. The driving module is configured to include a bracket, a sliding plate including a rack, a driving motor, and a driving gear. The driving module is coupled to a body and a moving plate after assembling the driving module so that it is possible to prevent a sliding plate which slidably moves together with a flexible display after assembling the flexible display device from being loosen and also prevent the idle operation of the driving gear.

Abstract: A flexible display device is provided. A flexible display device according to one embodiment of the present invention comprises a body, a moving plate, a first pulley, a second pulley, a driving track and a flexible display. The flexible display is coupled to outer surfaces of the moving plate and the driving track, and the driving track forms a continuous track shape by itself or together with the moving plate. Therefore, provided is the flexible display device in which a constant tension can be maintained over the entire section of the driving track while the moving plate and the driving track support the flexible display, the occurrence of spring back in the flexible display can be minimized, and damage caused by unevenness of the flexible display, and the like, can be prevented.
