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 device includes a first pixel, a second pixel, a first data line connected to the first pixel, and a second data line connected to the second pixel. Each of the first pixel and the second pixel includes a transistor including a conductive layer, a semiconductor layer on the conductive layer, a gate electrode on the semiconductor layer, and a source/drain electrode connected to the semiconductor layer, a capacitor including a first capacitor electrode in a same layer as the gate electrode and a second capacitor electrode on the first capacitor electrode, and a light emitting device on the transistor and the capacitor. The first data line is in a same layer as the source/drain electrode, and the second data line is in a same layer as one of the conductive layer and the second capacitor electrode.
