Abstract
A display device includes a pixel layer for displaying an image and a circuit layer including a thin film transistor for driving the pixel layer. The thin film transistor includes a semiconductor layer including a channel region and a source region and a drain region sandwiching the channel region, a first gate electrode facing the channel region on a first side which is either above or below the semiconductor layer, a second gate electrode facing at least the channel region and the source region on a second side opposite to the first side, a source electrode connected to the source region, and a drain electrode connected to the drain region. The source electrode penetrates through the semiconductor layer and is connected to the second gate electrode on the second side.
