Abstract

A thin film transistor includes an oxide semiconductor layer on a substrate. The oxide semiconductor layer includes a channel portion, a first channel connecting portion connected to a first end of the channel portion, and a second channel connecting portion connected to a second end of the channel portion. A thickness of the second channel connecting portion is different from a thickness of the first channel connecting portion. The first end of the channel portion has a same thickness as the thickness of the first channel connecting portion, and the second end of the channel portion has a same thickness as the thickness of the second channel connecting portion.
