An organic thin film transistor and a method for manufacturing the same is disclosed, which can improve the device properties by decreasing a contact resistance which occurs in a contact area between an organic semiconductor layer and source/drain electrodes. The organic thin film transistor includes a gate electrode formed on a substrate, a gate insulation layer formed on the gate electrode, source and drain electrodes overlapped with both edges of the gate electrode and formed on the gate insulation layer, an organic semiconductor layer formed on the gate insulation layer including the source/drain electrodes, a first adhesive layer having hydrophilic properties formed between the gate insulation layer and the source/drain electrodes, and a second adhesive layer having hydrophobic properties formed between the organic semiconductor layer and the gate insulation layer.
