Abstract: Disclosed are a cover window in which both a folding area and a non-folding area are formed using the same kind of material, thereby matching the indices of refraction thereof with each other, having the same heat resistance, and ensuring easy surface hard coating thereof, and a display device using the same. The cover window, having at least one folding area and a non-folding area, includes a hard portion located to correspond to the non-folding area, a soft portion located to correspond to the folding area, the soft portion being flexible, and a hard coating layer configured to cover the hard portion and the soft portion.

Abstract: A foldable display device includes a display panel including a first surface and a second surface opposite to the first surface; and an impact absorption film adjacent to the second surface of the display panel and including first and second impact absorption layers. The second impact absorption layer includes a soft part corresponding to a first region of the second impact absorption layer and a hard part corresponding to a second region of the second impact absorption layer. The first impact absorption layer and the soft part of the second impact absorption layer have an elastic modulus value less than an elastic modulus value of the hard part.

Abstract: Disclosed is a foldable display device which may reduce an amount of impact energy reaching a display panel, when external impact energy is transmitted, and thus protect the display panel. The foldable display device includes a display panel including at least one folding part and non-folding parts, a cover window attached to the upper surface of the display panel, and a frame configured to receive the display panel and the cover window and to pull one side and the other side of the cover window in opposite directions.
