An organic thin-film transistor manufacturing method and an organic thin-film
transistor manufactured by the method are disclosed, the method comprising the
steps of a) forming a gate electrode on a substrate, b) forming a gate insulating
layer on the substrate, c) forming an organic semiconductor layer on the substrate,
d) forming an organic semiconductor layer protective layer on the organic semiconductor
layer, e) removing a part of the organic semiconductor layer protective layer,
and f) forming a source electrode and a drain electrode at portions where the organic
semiconductor layer protective layer has been removed, so that the source electrode
and drain electrode contacts the organic semiconductor layer.
