1. A display apparatus comprising;
a driving circuit in a pixel of a substrate, the driving circuit including a first thin film transistor and a second thin film transistor; and
a light-emitting device in the pixel of the substrate, the light-emitting device electrically connected to the driving circuit,
wherein a first semiconductor pattern of the first thin film transistor includes an oxide semiconductor,
wherein the first semiconductor pattern includes a first channel region between a first source region and a first drain region,
wherein each of the first source region and the first drain region extends from the first channel region in an inclined direction with respect to a lower surface of the first channel region, such that a lower surface of the first source region and a lower surface of the first drain region opposite to the first channel region are disposed closer to the substrate than the lower surface of the first channel region, and
wherein the first thin film transistor includes a first source electrode connected to the first source region and a first drain electrode connected to the first drain region,
wherein each of the first source electrode and the first drain electrode is formed with a plurality of inclined steps.
