Abstract
A stretchable device includes a substrate, the substrate including first regions having a first stiffness and a second region between adjacent first regions and having a second stiffness that is lower than the first stiffness, a unit device array including unit devices on separate, respective first regions of the substrate, and an encapsulant covering the unit device array. The unit device array includes pixel electrodes isolated on separate, respective first regions of the substrate, common electrodes isolated on separate, respective first regions and each facing a separate pixel electrode, the stretchable device configured to apply a same voltage to the plurality of common electrodes, and active layers on separate, respective first regions and each between a separate pixel electrode and a separate common electrode.
