Abstract

An active matrix substrate () has multiple pixel areas. At least one pixel area includes a pixel TFT (), a pixel electrode (), a first circuit TFT (), and drive circuit wiring lines (Lto L) that are connected to the first circuit TFT. The pixel TFT () and the first circuit TFT () are oxide semiconductor TFTs. The pixel electrode () is formed from an upper transparent conductive film. The drive circuit wiring line includes a transparent wiring line portion (Land L) that is formed from a lower transparent conductive film which is positioned closer to a substratethan the upper transparent conductive film. At least one of a source electrode () and a drain electrode () of the first circuit TFT () is formed from the lower transparent conductive film.
