Patent ID: 8633523

Claim:
A thin film transistor, comprising: a substrate; a semiconductor layer formed on the substrate, the semiconductor layer including: a second channel region extending between a source region formed of the semiconductor layer and a second drain region which is spaced apart from the source region and is formed of the semiconductor layer, and; a first channel region intersecting the second channel region and connected to a first drain region which is spaced apart from the source region and from the second drain region and is formed of the semiconductor layer, a length of a portion of the second channel region, which extends between the second drain region and an intersection of the first and second channel regions, being different from a length of the first channel region; a gate electrode insulated from the semiconductor layer by a gate insulating layer; a source electrode connected to the source region of the semiconductor layer; a first drain electrode connected to the first drain region of the semiconductor layer; and a second drain electrode connected to the second drain region of the semiconductor layer.
