Abstract
An active matrix substrate includes a peripheral circuit including a TFT (A) supported on a substrate (). When viewed in a direction normal to the substrate (), a first gate electrode () of the TFT (A) includes a first edge portion and a second edge portion () opposing each other. The first edge portion and the second edge portion extend across an oxide semiconductor layer () in a channel width direction. At least one of the first edge portion and the second edge portion includes, in a region overlapping with the oxide semiconductor layer (), a first recess portion () recessed in a channel length direction and a first part () adjacent to the first recess portion in the channel width direction. When viewed in the direction normal to the substrate (), a source electrode () or a drain electrode () of the TFT (A) overlaps with at least a part of the first recess portion () and at least a part of the first part ().
