Abstract: A display device includes a housing, a display module, a support film, and a frame. The display module is accommodated in the housing in a first state and unrolled from the housing to a first direction in a second state. The support film is accommodated in the housing in the first state and unrolled from the housing to the first direction in the second state to support the display module. The frame shrinks to a first shape in the first state and expands to a second shape in the second state in a way such that the frame applies a tensile stress to the support film in the second state.

Abstract: A flexible display panel of an expandable display device includes a first side with a display unit, and a second side opposite to the first side. A bending guide includes an external guide that faces part of the first side and has a first curved side, and an internal guide that faces part of the second side and has a second curved side. A slider that slides on the bending guide is attached to, one end portion of the flexible display panel. A radius of the first curved side is greater than a radius of the second curved side. When the slider moves toward the bending guide, the first side contacts the first curved side and is bent by the first curved side, and when the slider moves away from the bending guide, the second side contacts the second curved side and is bent by the second curved side.
