Abstract
The present invention relates to minimizing a leakage current in a floating island portion formed in a thin film transistor. More specifically, the present invention is directed to a thin film transistor including: a source electrode and a drain electrode disposed above an insulating substrate at a predetermined interval; an s-Si film disposed in relation to the source electrode and drain electrode ; a gate insulating film overlapping the a-Si film ; and a gate electrode overlapping the gate insulating film , in which the a-Si film is disposed between the source electrode and the drain electrode and has a floating island portion above which or beneath which the gate electrode is not formed, and boron ions are implanted into this portion to form a boron-ion-implanted region
