Abstract: A display device includes a display panel including a display area on which a plurality of display elements is disposed and a non-display area on which one or more wires for driving the plurality of display elements are disposed. A back cover is attached to one surface of the display panel and has a plurality of openings. A roller unit winds or unwinds the back cover and the display panel, and a lifting unit moves the back cover and the display panel in a vertical direction. The plurality of openings overlaps the display panel, and each of the plurality of openings is disposed to be staggered with one or more of the openings in an adjacent row. A size of the back cover is larger than a size of the display panel.

Abstract: A display device may include a display panel, a first back cover disposed on a rear surface of the display panel, at least one flexible film which is electrically connected to one end of the display panel and is bent toward a rear surface of the first back cover or a front surface of the display panel, and a printed circuit board which is electrically connected to the at least one flexible film and disposed on the rear surface of the first back cover or the at least one flexible film. The printed circuit board overlaps one end of the display panel. Accordingly, one end of the display panel in which the pad area which is vulnerable to the stress is disposed and the printed circuit board are maintained to be flat, to minimize the damage of the display device.
