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.
