Abstract
An organic light emitting diode display includes a substrate, a scan line on the substrate for transferring a scan signal, a data line crossing the scan line and for transferring a data signal, a driving voltage line crossing the scan line and for transferring a driving voltage, a switching thin film transistor coupled to the scan line and the data line, a driving thin film transistor coupled to a switching drain electrode of the switching thin film transistor, and an organic light emitting diode (OLED) coupled to a driving drain electrode of the driving thin film transistor, wherein a driving semiconductor layer of the driving thin film transistor is bent and in a plane substantially parallel to the substrate.
