Abstract:
1. An organic thin film transistor (OTFT), comprising: a substrate; a gate electrode that is positioned on the substrate; a gate insulator that is positioned on the gate electrode and has a stacked structure comprising an inorganic gate insulator and an organic gate insulator; and an organic semiconductor layer that overlaps the gate electrode on the gate insulator, wherein the organic gate insulator is arranged on an entire surface of the substrate and encapsulates the inorganic gate insulator, wherein the organic gate insulator is disposed directly on the inorganic gate insulator and directly on the gate electrode, wherein the organic gate insulator has a uniform thickness greater than a thickness of the inorganic gate insulator, and wherein the thickness of the organic gate insulator is between 3000 Å to 10000 Å.
