Semiconductor packages are provided. A semiconductor package may include a semiconductor chip. The semiconductor package may include a substrate and first and second conductive regions on the substrate. In some embodiments, the substrate may be a flexible substrate, and the first and second conductive regions may be on the same surface of the flexible substrate. Display devices including semiconductor packages are also provided. In some embodiments, a display device may include a flexible substrate that is bent such that first and second conductive regions thereof are connected to each other via an intervening third conductive region.
