1. A display device comprising:
a base layer;
a circuit layer comprising a reinforcing layer disposed on the base layer and transistors disposed on the reinforcing layer, wherein each of the transistors comprises a semiconductor pattern comprising a source, an active, a drain, and a gate; and
a display layer comprising a light-emitting diode connected to the transistors,
wherein:
some of the semiconductor patterns of the transistors comprise polysilicon;
others of the semiconductor patterns of the transistors comprise oxide;
the reinforcing layer overlaps three or more actives among actives of the transistors; and
a distance from the reinforcing layer to a semiconductor pattern comprising the polysilicon is shorter than a distance from the reinforcing layer to a semiconductor pattern comprising the oxide.
