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.
