Abstract
Provided is a method of manufacturing a gradually stretchable substrate. The method includes forming convex regions and concave regions on a top surface of a stretchable substrate by compressing a mold onto the stretchable substrate and forming non-stretchable patterns by filling the concave regions of the stretchable substrate. The stretchable substrate includes a stretchable region defined by the non-stretchable patterns, the non-stretchable patterns have side surfaces in contact with the stretchable region, and the side surfaces of the non-stretchable patterns are formed of protrusions and a non-protrusion between the protrusions repetitively connected to one another.
