The organic thin film transistor array panel and a manufacturing method

Disclosed are an organic thin film transistor array panel and method for manufacturing the same. The organic thin film transistor array panel includes a substrate, a data line disposed on the substrate, a gate line intersecting the data line and including a gate electrode, a gate insulating layer disposed on the gate line and having a contact hole exposing the data line, a first electrode disposed on the gate insulating layer and electrically connected to the data line through the contact hole, a second electrode disposed opposite the first electrode with respect to the gate electrode, an organic semiconductor disposed on and contacting the first and the second electrodes, and a conductive stopper disposed on the organic semiconductor.
