Patent ID: 7994494

Claim:
An organic thin film transistor array panel comprising: a substrate; a data line formed on the substrate; a lower interlayer insulating layer formed on the data line; a gate line formed on the lower interlayer insulating layer, wherein the gate line intersects the data line and includes a gate electrode; an upper interlayer insulating layer formed on the gate line and the data line and having a first opening exposing the gate electrode; a gate insulator formed in the first opening; a source electrode disposed on the gate insulator and connected to the data line; a drain electrode opposing the source electrode; a pixel electrode disposed on the upper interlayer insulating layer and integrated with the drain electrode; an insulating bank formed on the source electrode and the drain electrode, the insulating bank defining a second opening which exposes portions of the gate insulator, the source electrode and the drain electrode; and an organic semiconductor formed in the second opening.
