Abstract
An active device and an active device array substrate are provided, wherein the active device array substrate includes a substrate and a plurality of active devices being located on the substrate, and at least one of the active devices includes a first thin film transistor and a second thin film transistor. The first thin film transistor is located on the substrate and has a first channel layer. The second thin film transistor stacks on the first thin film transistor, wherein the second thin film transistor has a second channel layer. The first thin film transistor and the second thin film transistor share a common gate electrode and the common gate electrode is located between the first channel layer and the second channel layer.
