Patent ID: 7863111

Claim:
A method of manufacturing a thin film transistor for display devices, the method comprising: forming a gate layer on a substrate; forming a first insulating layer on the substrate and the gate layer, and then forming a source and a drain on the first insulating layer; coating an active material on the first insulating layer, the source, and the drain to form an active layer; forming a second insulating layer on the first insulating layer, the source, the drain, and the active layer, and forming a via hole in the second insulating layer to expose the drain; and forming a drain connecting electrode by coating a Carbon Nanotube (CNT) dispersed conductive polymer in the via hole and on the second insulating layer, wherein the Carbon Nanotube (CNT) dispersed conductive polymer is a polymer in which a carbon nanotube powder is dispersed, wherein forming the first insulating layer and forming the source and the drain includes forming the source and the drain by coating and etching the Carbon Nanotube (CNT) dispersed conductive polymer on the first insulating layer.
