An electronic device is provided. The electronic device includes a substrate, an active element, a first insulation layer, and a detection element. The active element is disposed on the substrate. The first insulation layer is disposed on the active element. The detection element is disposed on the first insulation layer. The detection element comprises a lower electrode, an active layer and an upper electrode, and the lower electrode is a part of a conductive layer. The first insulation layer has a recess, and the recess does not overlap with the conductive layer in the normal direction of the substrate.
