Abstract: A display device includes a base layer, a circuit layer including a reinforcing layer disposed on the base layer and transistors disposed on the reinforced layer, where each of the transistors includes a semiconductor pattern including a source, an active, a drain, and a gate, and a display layer including a light-emitting diode connected to the transistors, where the reinforcing layer overlaps three or more actives among actives of the transistors. Some of semiconductor patterns of the transistors include polysilicon, others of the semiconductor patterns of the transistors include oxide, and a distance from the reinforcing layer to a semiconductor pattern including the polysilicon is shorter than a distance from the reinforcing layer to a semiconductor pattern including the oxide.
