Abstract
An active matrix substrate having a pixel region includes a terminal part, a guard ring, and a connection part that connects the terminal part and the guard ring to each other. The pixel region, the terminal part, and the guard ring each include a first conductive layer in which a first metal film and second metal films that are lower in resistance than the first metal film are stacked, a first protective layer disposed to overlap at least a part of the first conductive layer, and a second protective layer disposed over the first protective layer. The pixel region includes a second conductive layer provided at a higher level than the first protective layer. The connection part includes the first metal film and the second protective layer disposed over the first metal film. Ends of the first conductive layer in the terminal part and the guard ring that face the connection part are located on the inside of ends of the first protective layer that face the connection part. The second conductive layer and the second metal films contain materials that are etchable with an identical etchant.
