Patent ID: 7776666

Claim:
A method of manufacturing a thin film transistor which includes at least a gate electrode, a semiconductor layer, a source electrode and a drain electrode on a transmissive substrate, the method comprising: forming the gate electrode on the substrate; forming a gate insulation layer on the gate electrode; forming the semiconductor layer on the gate insulation layer; forming a repellent layer on the semiconductor layer, the repellent layer being repellent to a fluid electrode material; applying light to simultaneously remove both a part of the semiconductor layer and a part of the repellent layer other than an area shaded from the light by the gate electrode, by applying the light from an opposite surface of the substrate to a surface of the substrate on which the gate electrode is formed; and forming the source electrode and the drain electrode by dropping the fluid electrode material on the repellent layer and dividing the fluid electrode material by the repellent layer.
