Abstract
The present invention relates to an organic thin film transistor (OTFT), a method of fabricating the OTFT, and an organic electroluminescent display that has the OTFTs. The invention prevents surface damage of an organic semiconductor layer and reduces an off-current. The OTFT includes a substrate, a source electrode and a drain electrode formed on the substrate, and a semiconductor layer formed on the substrate that has a channel layer disposed over and between the source electrode and drain electrode. In addition, the OTFT includes a gate insulating layer formed on the semiconductor layer, a separation pattern formed through the semiconductor layer and the gate insulating layer to separate the channel layer, and a gate electrode formed on the gate insulating layer over the channel layer.
