Abstract: The present application provides a display device that includes a flexible display panel and a panel support device. The panel can be rolled up or stretched out along a first direction, and the support device includes an elastic member and movable members. The elastic member includes protrusion portions and groove portions alternately arranged along the first direction, the protrusion portion is fixed on a back surface of the panel, the groove portion and the back surface forms a strip-shaped cavity, and the width of the groove portion in an initial state gradually decreases along a direction approaching the panel. The movable members respectively and movably arranged in the cavities. When the movable member moves in the cavity, towards a side of the cavity close to the panel, the movable member supports and separates ends of two side walls of the groove portion close to the panel more apart.
