THIN-FILM TRANSISTOR, LIQUID-CRYSTAL DISPLAY DEVICE, AND METHOD OF PRODUCING THE SAME

摘要

When a thin-film transistor (TFT) is formed on a glass substrate, electric charges caused in the TFT can be removed so as to avoid electrostatic damage in the TFT. A short-circuiting pattern that short-circuits the source region and the drain region of the TFT is added to a polysilicon pattern that constitutes the TFT. This short-circuiting pattern is removed at the same time as or after the wiring formation in the source region and the drain region.
