Abstract
A thin film transistor is circular when viewed from top. A first source/drain region is disposed at the center, a semiconductor layer surrounds the first source/drain region and overlaps with an external periphery of the first source/drain region, and a second source/drain region surrounds the semiconductor layer and overlaps the external periphery of the semiconductor layer. The potential of the second source/drain region is set higher than the potential of the first source/drain region. The external periphery of the first source/drain region and the internal periphery of the second source/drain region have concentric circular shapes.
