A display apparatus includes a substrate, a semiconductor layer on the substrate, the semiconductor layer including an oxide semiconductor, a channel region and a first region which extends from the channel region to a first edge of the semiconductor layer and has a lower resistance than that of the channel region, a first inorganic insulating layer covering the semiconductor layer and including a first contact hole which overlaps the first region, a first electrode on the first inorganic insulating layer, overlapping the first region and electrically connected to the first region through the first contact hole, a gate electrode on the first inorganic insulating layer and overlapping the channel region, a second inorganic insulating layer covering the first electrode and the gate electrode, and a display element on the second inorganic insulating layer.
