According to an aspect, an array substrate includes a first scan line, a second scan line, and a signal line. A semiconductor film has a coupling portion coupling one end of a first linear portion to one end of a second linear portion. Another end of the first linear portion of the semiconductor film and another end of the second linear portion of the semiconductor film are coupled to the signal line. In a plan view, the semiconductor film is disposed between the first scan line and the second scan line, the first linear portion intersects two first gate electrodes, and the second linear portion intersects two second gate electrodes.
