Abstract
A semiconductor film 21 is provided so as to overlap with a light-shielding film 11 when viewed in a plan view. A second insulating film 30 has a contact hole CH1 that reaches a source electrode 22 and a drain electrode 23. A gate electrode 41 is provided on the second insulating film 30 so as to overlap with the semiconductor film 21 when viewed in a plan view, and at the same time, so as to overlap with none of the source electrode 22 and the drain electrode 23 when viewed in a plan view. A third insulating film 50 is provided on the second insulating film 30 so as to cover the gate electrode 41, and at the same time, so as to be in contact with the source electrode 22 and the drain electrode 23 through the contact hole CH1.
