Claim Text:
1. A method of manufacturing a gradually stretchable substrate, the method comprising: disposing a photomask on a photo-curable stretchable substrate, the photomask including an edge portion and a central portion; and exposing an edge region of the stretchable substrate to a first dose of light through holes in the edge portion, and a central region of the stretchable substrate to a second dose of the light through holes in the central portion, the first dose of light being lower than the second dose of light; forming an electric device directly on the exposed stretchable substrate by forming a gate electrode directly on the central region, and forming a gate insulating layer directly on the edge region, wherein the central region has a smaller intensity of stretchability than the edge region.
