Abstract: A rollable display device is provided. The rollable display device includes first and second bodies, a display, a roller supported in the first body to be rotatable, to which one end portion of the display in a length direction of the display is fixed and around an outer circumference of which the display is wound, and a support member a plurality of segmented links connected to pivot around a hinge shaft perpendicular to an image display surface, the support member being accommodated in an accommodation unit provided in the first body. As the first body is separated from the second body, the display is unwound from the roller and is unrolled outward from the first body to expand in the length direction, and the support member is unrolled outward from the first body in the length direction to support a rear surface of the display.
