Abstract
A pixel circuit includes a substrate, and a first thin film transistor and a second transistor which are disposed on the substrate. The first thin film transistor is in a top-gate structure, and the second thin film transistor is in a bottom-gate structure; a first electrode of the first thin film transistor is electrically connected with a gate electrode of the second thin film transistor, and the first electrode of the first thin film transistor and the gate electrode of the second thin film transistor are in a same layer on the substrate. The pixel circuit can have a relatively high switch speed and a relatively large driving current, a manufacturing method is easily realized and a process cost is relatively low.
