Abstract:
1. A thin film transistor structure of a pixel, comprising: a first metal layer, which comprises a gate electrode, and a gate electrode portion extending from the gate electrode; an insulating layer disposed on the first metal layer; an amorphous silicon layer disposed on the insulating layer, the amorphous silicon layer being respectively disposed above the gate electrode and above the gate electrode portion; and a second metal layer disposed on the amorphous silicon layer, the second metal layer comprising a drain electrode and a source electrode, the source electrode being disposed on the amorphous silicon layer above the gate electrode, one portion of the drain electrode extending to the amorphous silicon layer above the gate electrode and another portion of the drain electrode extending above the gate electrode portion respectively, and the drain electrode partially overlapping the gate electrode and the gate electrode portion respectively with the amorphous silicon layer interposed therebetween.
