Patent ID: 6998640

Claim:
A thin film transistor substrate, comprising at least: a first stack structure and a second stack structure on the substrate, wherein the first stack structure comprises layers successively disposed which are a first conduction layer, a first insulation layer, and a semiconductor layer, and the second stack structure at least includes a second conduction layer; an ohmic contact layer on a first region and a second region of the semiconductor layer, where the first region and the second region are disconnected; a second insulation layer, positioned at least on the side surfaces of the first stack structure and the second stack structure and a part of the upper surface of the second stack structure; a source electrode and a drain electrode, wherein the source electrode is positioned on a part of the second insulation layer and the ohmic contact layer in the first region, and the drain electrode is positioned on a part of the second insulation layer and the ohmic contact layer in the second region; a passivation layer, positioned on the semiconductor layer, the source and the drain electrodes, and the second insulation layer; and a transparent conduction layer, disposed on the passivation layer, wherein a first portion of the transparent conduction layer is electrically coupled to one of the source and the drain electrode and a second portion of the transparent conduction layer is electrically coupled to the second conduction layer of the second stack structure.
