    Abstract: A display device includes a first display area and a second display area adjacent to the first display area in a first direction, driving elements, light-emitting elements including a pixel electrode electrically connected to a corresponding one of the driving elements, signal wirings that transfer a driving signal to the driving elements, and connection wirings that transfer a driving signal to signal wirings disposed in the second display area. At least one of the connection wirings includes a first signal-transferring portion extending in the first direction, a second signal-transferring portion extending in a second direction, and dummy portions extending in a direction intersecting the first and second signal-transferring portions. The pixel electrode overlaps a gap between dummy portions of adjacent connection wirings in an area where the connection wirings are disposed.

    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.
