Abstract: A foldable display device includes a foldable display panel and a foldable cover window disposed on the foldable display panel. The foldable cover window includes a flexible film and a first hard coating layer located on the flexible film with the first hard coating layer including a base material in combination with a linker material. The base material is a siloxane-based resin and the linker material is one of: a urethane-acrylic-based linker, an acrylic-based linker, and an epoxy-based linker.

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.
