A window includes a base layer, a high refractive layer which is disposed on the base layer and includes a first polymer derived from a first resin composition containing a highly stretchable material, and a low refractive layer which is disposed on the high refractive layer and includes a second polymer derived from a second resin composition containing hollow particles and a first initiator including and fluorine. The highly stretchable material is represented by Formula A-1 or Formula A-2 below, and the second resin composition contains about 5 wt % or less of the first initiator with respect to the total amount of the second resin composition.
