Abstract: Provided is a display device. The display device includes: a flexible display panel, a roller fixed to a lower edge of the display panel, a plurality of links having one end connected to an upper edge of the display panel, a driving unit which is disposed proximate the roller and configured to rotate the roller, and an elastic member which is connected to the other end of each of the plurality of links and disposed outside of the roller. Accordingly, the force of the driving unit is directly transmitted to the roller and the force of the elastic member is directly transmitted to the links, such that the configuration and operation of manipulating the display device between a rolled configuration and an unrolled configuration is simplified.

Abstract: A rollable display device includes a roller having a cylindrical shape and an outer circumferential surface on which a display panel is rolled. A cylinder member supports rotation of the roller, using a rotation support member coupled thereto. A housing member is rotatable together with the roller. A torsional elastic member is fixed to the cylinder member and the housing member. A housing inner member is provided on an inner circumferential surface of the housing member, such that impurities are attached thereto. Noise is prevented from being generated by impurities due to friction during operations, and impurities are prevented from moving outwardly.
