A method for manufacturing a display device is provided in which an a-Si semiconductor layer including signal terminal regions is formed in an island manner and the total parasitic capacitance is minimized while the increase of the number of process steps for photolithography is restricted. Signal lines, signal lead wires, signal terminals, part of drain electrodes, and part of source electrodes are formed using thin portions of a resist pattern. Small regions each from the position where a drain electrode and a source electrode oppose each other to positions beyond the width of a gate electrode are formed using the thick portions of the resist pattern. The resist pattern having these portions is used as a mask to etch a metal layer and a contact layer, and is reflowed to form a reflowed resist mask. The reflowed resist mask is used to form semiconductor islands.
