Abstract: The invention provides a thin film semiconductor element and a method of manufacturing the same to achieve lowering the resistance of gate electrodes, lowering the capacitance of source electrodes, and enhancing etching characteristics. The thin film semiconductor element can include a semiconductor film provided on a substrate, source and drain electrodes connected to the semiconductor film, and a gate electrode provided on the semiconductor film with an insulating film interposed therebetween. The film thickness of the source and drain electrodes can be smaller than the film thickness of the gate electrode.
