Abstract: A display device includes a pixel including a thin film transistor, and an under layer below the thin film transistor. The thin film transistor includes a first gate electrode, a semiconductor layer and a second gate electrode. The semiconductor layer includes a channel region that overlaps at least one of the first gate electrode and the second gate electrode in a plan view. The channel region curves in a thickness direction of the semiconductor layer. The first gate electrode includes a first edge located on the side of an edge of the channel region in a direction of a channel length. The second gate electrode includes a second edge located on the side of the edge of the channel region. The position of the first edge is different from the position of the second edge in the direction of the channel length.
