Abstract: An organic fight-emitting display device comprises a first thin-film transistor disposed on a substrate; and a second thin-film transistor disposed on the substrate and spaced apart from the first thin-film transistor. The first thin-film transistor comprises a first semiconductor layer, a first conductive layer disposed on the first semiconductor layer and that overlaps the first semiconductor layer, and a first insulating layer disposed between the first semiconductor layer and the first conductive layer. The second thin-film transistor comprises a second semiconductor layer, and a second conductive layer disposed on the second semiconductor layer and that overlaps the second semiconductor layer. The first semiconductor layer is disposed on a layer higher than the second semiconductor layer, the first semiconductor layer comprises an oxide semiconductor, the second semiconductor layer comprises low temperature polycrystalline silicon (LTPS), and the first insulating layer covers the entire first semiconductor layer.

Abstract: A display panel includes two or more gate layers including a plurality of gate patterns extending in a first direction and one or more source-drain layers including a plurality of source-drain patterns extending in a second direction crossing the first direction. The gate patterns of the two or more gate layers are curved or bent along a hole surrounding area corresponding to a periphery of a hole in an active area. The source-drain patterns of the one or more source-drain layers are curved or bent along the hole surrounding area. The gate patterns of at least one of the two or more gate layers overlap the source-drain patterns of at least one of the one or more source-drain layers in a thickness direction of the display panel in the hole surrounding area.
