An electronic apparatus includes a flexible display device and a roller. The flexible display device includes a driving substrate, a display layer on the driving substrate, and a front protective layer covering the display layer. The flexible display device has an end portion fixed to the roller. The roller includes a holding groove, a receiving slot, and a retraction assembly. The holding groove is recessed from an external surface of the roller. The end portion is in the holding groove. The flexible display device further includes a main body portion outside the holding groove. A thickness of the end portion is less than a thickness of the main body portion. The receiving slot is recessed from the external surface. The retraction assembly is disposed in the receiving slot. When the retraction assembly abuts against the flexible display device, the retraction assembly is pressed into the receiving slot.
