Abstract

According to the insulated gate transistor, a gate electrode (A) is provided on a main surface of a glass substrate (); a first part of an insulating layer (gate insulating layer () and transparent inorganic insulating layer ()) is thicker than a second part of the insulating layer (gate insulating layer ()), the first part being between (i) the gate electrode (A) and (ii) a source electrode () and a drain electrode () of the insulated gate transistor, and the second part being between (i) the gate electrode (A) and (ii) a channel section (A) of the insulated gate transistor. This makes it possible to reduce parasitic capacitor without deteriorating characteristics of the transistor.
