A window for a display device that includes: a base substrate; a first coating layer disposed on a first surface of the base substrate; and a second coating layer disposed on a second surface that overlaps the first surface of the base substrate, wherein the base substrate further includes a vertical surface perpendicular to the first surface and the second surface, and the first coating layer overlaps the vertical surface. The impact resistance of the window is improved through the first coating layer covering the rear surface and the vertical surface of the base substrate.
