Abstract: Provided is an electronic device. The electronic device includes a first semiconductor layer and a second semiconductor layer sequentially stacked on a substrate and a source electrode, a gate electrode, and a drain electrode arranged on the second semiconductor layer. The electronic device further includes a field plate which is electrically connected to the source electrode and extends towards the drain electrode, wherein the field plate becomes farther away from the substrate as the field plate becomes closer to the drain electrode.
