A display device comprising:
- a flexible display panel;
- a roller which extends in a long direction, and around which the flexible display panel is wound, or from which the flexible display panel is unwound;
- and
- a disc wheel which is located adjacent to edges of flexible display panel which is wound around the roller, which crosses a rotation shaft of the roller, and which is coupled to the roller,
- wherein a diameter of the disc wheel is larger than a diameter of the flexible display panel wound around the roller,
- wherein the disc wheel comprises:
- an inner circle fixed to the roller;
- a first outer circle which forms a step toward an outer side in a rotation shaft direction of the roller from a circumference of the inner circle;
- and
- a second outer circle which faces the outer circle with respect to the inner circle, and which forms a step inward in the rotation shaft direction of the roller.
