Zusammenfassung:Embodiments of the present invention provide a rollable display device. The rollable display device comprises: a cylindrical roller on which a display panel is wound on an outer circumferential surface; a cylinder member to which a rotation support member is coupled to support rotation of the roller; a housing member rotating together with the roller; a torsional elastic member fixed to the cylinder member and the housing member; and a housing inner member provided on an inner circumferential surface of the housing member to which foreign matters are attached. The display panel may be rolled to implement a rollable display rolled up and unfolded. The rollable display device may prevent noise due to the foreign matters or external leakage of the foreign matters generated by friction during operation. 본 실시예들은, 외주면에 디스플레이 패널이 감기는 원통형상의 롤러, 롤러의 회전을 지지하도록 회전지지부재가 결합되는 실린더부재, 롤러와 함께 회전하는 하우징부재, 실린더부재와 하우징부재에 고정되는 비틀림탄성부재, 하우징부재의 내주면에 구비되어 이물질이 부착되는 하우징 내측부재를 구비하여 디스플레이 패널이 롤링되어 말리고 펼쳐지는 롤러블 디스플레이를 구현할 수 있으며, 작동중 마찰로 발생되는 이물질로 인한 소음이나 이물질의 외부 유출을 방지할 수 있는 롤러블 디스플레이 장치를 제공한다.
