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 support plate, a method of manufacturing the same, and a foldable display device including the same. The support plate is provided on a bottom portion of a back plate bendable about a folding axis. The support plate includes a support layer. The support layer includes one or more prepregs each comprising a resin and carbon fibers. The support plate is provided in a semi-cured state, and is attached to the bottom portion of the back plate without an adhesive. The support plate is enabled to be folded without an open area pattern.
