An electronic device is provided. The electronic device includes a substrate, a thin-film transistor, a first organic layer, a conductive layer, a second organic layer and a photoresist element. The thin-film transistor is disposed on the substrate. The first organic layer is disposed on the thin-film transistor and has a through-hole. The conductive layer is disposed on the first organic layer and electrically connected to the thin-film transistor through the through-hole. The second organic layer includes a first portion and a second portion. The first portion of the second organic layer is disposed in the through-hole, and the second portion of the second organic layer covers at least a portion of a flat portion of an upper surface of the first organic layer. The photoresist element is disposed on the second organic layer.
