Abstract
A thin film transistor includes: a gate electrode; source and drain electrodes insulated from the gate electrode; an organic semiconductor layer that is insulated from the gate electrode and electrically connected to the source and drain electrodes; an insulating layer that insulates the gate electrode from the source and drain electrodes or the organic semiconductor layer; a hydrophobic layer which covers the source and drain electrodes or insulating layer and has an opening that defines a region corresponding to the organic semiconductor layer; and a hydrophilic layer formed in the opening of the hydrophobic layer, wherein the organic semiconductor layer is formed on the hydrophilic layer. The thin film transistor includes the organic semiconductor layer having a highly precise pattern that is formed without an additional patterning process.
