Abstract:
A method of producing a thin-film transistor on an insulating substrate, comprising the steps of:forming a polysilicon pattern on the insulating substrate, the polysilicon pattern including a first region of a first conductivity, a second region of the first conductivity, a first bridging region that connects the first region and the second region, and a second bridging region that also connects the first region and the second region; forming an insulating film on the insulating substrate in such a manner that the insulating film covers the polysilicon pattern; forming a gate electrode pattern on the insulating film in such a manner that the gate electrode pattern covers the first bridging region; forming a wiring pattern on the first region in such a manner that the wiring pattern is in contact with the first region; and cutting the second bridging region after the step of forming the wiring pattern.
