Abstract: A window is provided to include a glass substrate, an adhesive layer on the glass substrate, a polymer layer between the glass substrate and the adhesive layer, the polymer layer having a surface adjacent to the adhesive layer, the surface being hydrophilic at a first temperature and being hydrophobic at a second temperature higher than the first temperature, and a protective layer on the adhesive layer. Thereby, when the protective layer is damaged, only the protective layer may be replaced without replacing a glass substrate.
