Abstract
A stretchable display device includes a substrate having a plurality of islands spaced apart from each other, and a plurality of bridges connecting each of the plurality of islands. A plurality of display units is disposed above the plurality of islands, respectively. A plurality of metal wirings are electrically connected to each of the plurality of display units. The plurality of metal wirings are disposed above the plurality of bridges. Each of the plurality of bridges includes a first region curved convexly in a first direction on a plane, and a second region curved concavely in the first direction. The second region is connected to the first region. Each of the plurality of metal wirings has a first width, and each of the plurality of bridges have a second width that is greater than the first width.
