1. An organic light emitting diode (OLED) display including:
a substrate; an organic light emitting element formed on the substrate; a first thin film transistor providing driving power to the organic light emitting element, the first thin film transistor includes an amorphous silicon channel region; and a plurality of other thin film transistors directly connected to the first thin film transistor, each of the plurality of other thin film transistors includes a polysilicon channel region which is directly connected to the amorphous silicon channel region, wherein a distance between a first gate electrode and the amorphous silicon channel region of the first thin film transistor being longer than a distance between a gate electrode and the polysilicon channel region of the plurality of other thin film transistors.
