Abstract: A foldable display device includes a window. The window includes a first sub window, a second sub window, and an adhesive layer for coupling the first sub window and the second sub window to each other. The first sub window includes a first base layer having light transmittance of 90% or more and a first anti-fingerprint layer disposed on an upper surface of the first base layer, and the second sub window includes a second base layer disposed on the first sub window. A contact angle of a folding area of an upper surface of the first sub window is less than a contact angle of a peripheral area of the upper surface of the first sub window.

Abstract: A foldable display device is capable of improving a strength of a folding area and substantially reducing or minimizing a dead space of a non-folding area. The foldable display device includes: a display panel including a folding area and a non-folding area, and having a front surface and a back surface that are opposite each other; a window adjacent the front surface of the display panel; an auxiliary layer adjacent the back surface of the display panel; a first adhesive layer between the display panel and the window; and a second adhesive layer between the display panel and the auxiliary layer. A width of the window at the folding area is greater than a width of the window at the non-folding area.
