| 摘要 |
A first-conductivity-type thin film transistor and a second-conductivity-type thin film transistor are formed using a plurality of single crystal grains, the plurality of single crystal grains being formed substantially centered on each of a plurality of starting-point portions disposed on an insulating surface of a substrate, the plurality of single crystal grains being composed of at least a first single crystal grain and a second single crystal grain adjacent to each other, with a crystal grain boundary therebetween, the first-conductivity-type thin film transistor includes at least a first-conductivity-type drain region formed adjacent to the crystal grain boundary in the first single crystal grain, the second-conductivity-type thin film transistor includes at least a second-conductivity-type drain region formed adjacent to the crystal grain boundary in the second single crystal grain, and a common electrode is provided on the crystal grain boundary to lead out outputs from the first-conductivity-type drain region and the second-conductivity-type drain region.
