    Abstract: A display apparatus is disclosed that includes contact holes formed to expose at least a portion of a conductive layer or a semiconductor layer without damage to the surface of the conductive layer or the semiconductor layer, and a method of manufacturing the display apparatus. The display apparatus includes a substrate, a conductive mound arranged on the substrate, a first insulating mound arranged on the substrate, and a semiconductor layer including a first region arranged on the conductive mound, and a second region arranged on the first insulating mound. The second region of the semiconductor layer substantially covers an upper surface of the first insulating mound.

    Abstract: A display apparatus includes a thin film transistor facing a substrate with a buffer layer therebetween and including a semiconductor layer, a channel region, a source region, a drain region, and a gate electrode; a conductive pattern between the substrate and the semiconductor layer and connected to the semiconductor layer, the conductive pattern facing the semiconductor layer with the buffer layer therebetween; a contact hole in the buffer layer and exposing the conductive pattern to outside the buffer layer; and a display element which is electrically connected to the thin film transistor. The source region or the drain region extends through the contact hole in the buffer layer, to contact the conductive pattern and connect the semiconductor layer to the conductive pattern.
