Generally, a flexible display panel is a display panel which can be bent at a predetermined curvature. Since such a flexible display panel uses a plastic substrate rather than a commonly used glass substrate, a low-temperature manufacturing processor is used instead of a conventional manufacturing processor in order to prevent damage to the substrate.

Such a flexible display panel is manufactured, for example, as a touch screen capable of electrostatic or pressure-sensitive touch input so as to receive a user's command in a touch manner.

Meanwhile, the conventional portable foldable display device has a flexible display panel capable of touch input as described above. In the conventional foldable display device, a folded portion of the flexible display panel forms a predetermined accommodating space in which a pair of bodies supporting the flexible display panel are curved.

A patent document similar to the folding hinge device for a flexible display according to the present invention includes the disclosure number 10-2015-0096827, entitled " Hinge device of the invention and a foldable display device having the same.
