Abstract
A rollable display apparatus including a display panel having a threshold curvature radius; a roller, having a curvature radius equal to or larger than the threshold curvature radius, attached to one side of the display panel and configured to allow the display panel to be rolled-up; and a curved surface member, spaced apart from the roller, having a curvature radius equal to or larger than the threshold curvature radius in an area in contact with the display panel, configured to bend the display panel in a direction opposite to a direction in which the display panel is rolled by the roller.
