Abstract
An active matrix substrate having low susceptibility to contact failure between two conductor films is provided. An oxide semiconductor film converted into a conductor is provided in a layer between a substrate and a first metal film. Within a contact hole, the oxide semiconductor film converted into a conductor is in contact with a second metal film. Outside of the contact hole, the oxide semiconductor film converted into a conductor is in contact with the first metal film.
