Abstract

A display device includes a flexible display panel; a rolling driver including a rolling shaft connected to the flexible display panel and a rotation motor which rotates the rolling shaft; a housing which receives the flexible display panel in a rolled state, where a first opening is defined in the housing for unrolling and rolling the flexible display panel; a rolling stopper coupled to the flexible display panel; and a rolling controller which controls the rolling driver such that the rotation motor rotates in a clockwise or counterclockwise direction. The rolling controller rotates the rotating motor in a direction opposite to a rotating direction of the rotation motor for a previous rolling to unroll the flexible display panel. The rolling controller rotates the rotating motor in a same direction as a rotating direction of the rotation motor for a previous unrolling to roll the flexible display panel.
