Abstract
The rollable display device of the present invention includes a base, a cover, a rolling module, a display screen, an actuating unit and a supporting unit. When an external force is applied on the cover to switch the display screen from a retracting state into an expanding state, the display screen rolled on the rolling module would expand out of the base.
