Methods for manufacturing semiconductor devices according to embodiments of the present invention may include providing a sacrificial substrate including a wiring region and a device region, sequentially forming a sacrificial layer and a buffer layer on the sacrificial substrate, forming a thin-film transistor on the buffer layer of the device region, forming a device protection element surrounding the thin-film transistor within the device region, forming a flexible substrate on the buffer layer, and exposing a surface of the buffer layer by separating the sacrificial substrate by removing the sacrificial layer. Since typical semiconductor process technologies may be directly used, the process compatibility may be improved, and semiconductor devices having high resolution and high performance may be manufactured. Furthermore, since the thin-film transistor is protected by the device protection element, the deformation of semiconductor devices under flexibility conditions may be prevented, thereby improving the reliability of the semiconductor devices.
