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.
