Abstract:
An organic light-emitting display apparatus including a switching thin film transistor (TFT) on a substrate, wherein the switching TFT is electrically coupled to a scan line and a data line, a driving TFT electrically coupled to the switching TFT, the driving TFT including a driving semiconductor layer, and an organic light-emitting diode (OLED) electrically coupled to the driving TFT, wherein the driving semiconductor layer includes a first region bending from a first direction to a second direction that intersects with the first direction a second region bending from the second direction to the first direction, and a third region coupling the first region to the second region, the third region making an obtuse angle with each of the first region and the second region.
