Abstract
A display apparatus includes a roller extending in a first direction and a display module coupled to the roller. The roller includes a cylinder body having an inner accommodation space, and the cylinder body defines a slot that exposes the inner accommodation space to the outside and extends in the first direction. An outer surface of the cylinder body includes a support surface spaced apart from an axis of the cylinder body by a first distance and a guide surface extended to or from the support surface and recessed a predetermined distance toward the axis such that a distance to the axis is less than the first distance. The guide surface is extended to or from a first end of the slot.
