Abstract
Disclosed is a thin film transistor including an active pattern including a first conductive region, a first channel region adjacent to the first conductive region, a second conductive region spaced apart from the first conductive region, a second channel region spaced apart from the first channel region, and a third conductive region spaced apart from the second conductive region, and a gate electrode positioned on the active pattern and including a first gate region crossing the first channel region, a second gate region crossing the second channel region, and a connection gate region connecting the first gate region. The connection gate region, the first gate region, and the second gate region together surround the second conductive region.
