Abstract
An embodiment of the present invention provides a stretchable substrate that may be significantly stretchable to be deformed but have a low rate of breakage. Here, the stretchable substrate includes a cell, a cut portion, and an extended cut line. A plurality of cells are formed in the substrate body, and a device is mounted thereon. The cut portion is formed in the substrate body to increase a distance between the cells when the substrate body is stretched. The extended cutting line is formed to extend from an end portion of the cut portion and bent inwardly of the cell so that corners of the cells are rounded.
