Abstract: Provided is a method of manufacturing a stretchable substrate having improved thickness deformation uniformity through control of a spatial crosslinking degree according to various embodiments of the present disclosure to implement the above object. The method includes forming a substrate part of an elastic material, forming an auxetic including a plurality of unit structures on the substrate part, and forming a fixing part on the substrate part on which the auxetic is formed, wherein the fixing part has a different vertical crosslinking density at each position.
