Abstract: A flexible display device can include a display panel configured to display images. The display panel includes at least one folding area that is foldable about a folding axis and a non-folding area. A cover window is provided on the display panel. Aback plate supports a bottom portion of the display panel, and a support part supports the back plate in a slidable manner. Further, a first magnetic body is connected to the cover window or the back plate. A second magnetic body is also provided on the support part to attract the first magnetic body so that a portion of the second magnetic body connected to the first magnetic body is drawn from the folding area toward the non-folding area. As such, a crease that can develop in the folding area can be prevented from forming by applying tension to the display panel.

Abstract: A display device includes a display panel having a display area and a non-display area surrounding the display area, and a decorative film disposed on the display panel. The decorative film includes a porous layer disposed on the display panel and including a plurality of pores, and a decorative layer which overlaps the non-display area and is disposed in the porous layer. Accordingly, the decorative layer which is partially disposed is formed in the porous layer so that a step caused by the decorative layer is not formed or minimized to reduce the thickness of the decorative film. As a result, the design the display device can be slim, and a flexible display device with an excellent folding reliability can be provided based on the display device.

Abstract: A display device includes a display panel, a refraction index matching layer disposed on the display panel and including a non-adhesive material, a first protective film disposed on the refraction index matching layer, and a supporting unit including a horizontal portion, a side portion vertically bent from the horizontal portion, and a protrusion portion vertically bent from the side portion and disposed on the protective film. Further, the display panel, the refraction index matching layer, and the protective film are seated on the horizontal portion of the supporting unit. Therefore, the folding characteristic is excellent and the protective film may be easily replaced without causing the damage on the display panel if necessary.
