Patent ID: 7838872

Claim:
An organic thin film transistor array panel comprising: a substrate; a data line disposed over the substrate; an insulating layer disposed over the data line and having a contact hole extending to the data line; a first electrode disposed over the insulating layer and connected to the data line through the contact hole; a second electrode disposed over the insulating layer; an electrically insulative material having an opening defined therein and disposed over the insulating layer, the first electrode and the second electrode, where the opening exposes the first and second electrodes; an island-shaped semiconductor disposed inside and contained by the opening, the island-shaped semiconductor being disposed over the exposed first and the second electrodes and having an outer boundary of its island shape defined by said opening which contains it; an island-shaped gate insulator disposed inside and contained by the opening, the island-shaped gate insulator being disposed over the island-shaped semiconductor and having an outer boundary of its island shape defined by said opening which contains it; and a gate electrode disposed on the island-shaped gate insulator; wherein at least one of the island-shaped semiconductor and the island-shaped gate insulator is composed of a respective organic material.
