1. An organic light-emitting display apparatus comprising:
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 comprising a driving semiconductor layer; and an organic light-emitting diode (OLED) electrically coupled to the driving TFT, wherein the driving semiconductor layer comprises:
a first region comprising a first curved region bending from a first direction to a second direction that intersects with the first direction;a second region comprising a second curved region bending from the second direction to the first direction; anda 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,wherein the first and second curved regions each comprise an inner corner and an outer corner opposite the inner corner across a respective one of the first and second curved regions, wherein a radius of curvature of the outer corner is greater than a radius of curvature of the inner corner.
