Abstract: An electronic device includes a substrate, a first transistor, a second transistor, an electronic unit and a conductor. The first transistor is disposed on the substrate and comprises a first semiconductor layer. The second transistor is disposed on the substrate and comprises a second semiconductor layer, wherein a material of the first semiconductor layer is different from a material of the second semiconductor layer. The electronic unit is disposed on the substrate and electrically connected to the second transistor. The conductor is electrically connected to the first semiconductor layer and the second semiconductor layer.
