Abstract
A display apparatus includes a substrate, a first thin-film transistor including a first semiconductor layer on the substrate, and a first gate electrode on the first semiconductor layer, the first gate electrode being insulated from the first semiconductor layer by a first gate insulating layer, an organic interlayer insulating layer covering the first gate electrode, a first conductive layer on the organic interlayer insulating layer, a first contact hole exposing a top portion of the first semiconductor layer by penetrating through the organic interlayer insulating layer and the first gate insulating layer, and a first protruding portion protruding from a top surface of the substrate between the substrate and the first semiconductor layer, the first protruding portion corresponding to the first contact hole, wherein the first conductive layer contacts the first semiconductor layer through the first contact hole.
