Abstract: A foldable display device includes a display panel configured to be folded around a folding axis. The display panel includes spacers disposed in a non-folding area and a folding area, and the spacers may have different sizes or densities. Dimensions of the spacers may be in a direction of the folding axis or intersect the direction of the folding axis. The display panel also includes pixels in an active area that overlap with the spacers, which may help reduce peeling, cracking, defects, or reduction in pixel brightness due to folding of the display device.

Abstract: A foldable display device includes a display panel which includes a folding area and non-folding areas on some sides of the folding area, and a hinge unit which is disposed in an area corresponding to the folding area below the display panel to in-fold or out-fold the display panel. The hinge unit includes a plurality of rotary shafts and a plurality of coupling links disposed between the plurality of rotary shafts. Accordingly, the foldable display device can be bi-directionally (e.g., inwardly or outwardly) folded by the hinge unit with a simple structure. Further, a radius of curvature during the folding can be desirably changed by adjusting a component of the hinge unit, for example, a number of the plurality of rotary shafts and the plurality of coupling links, a cross-sectional length, and the like.

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.
