<p>A thin film transistor includes a gate electrode formed on a substrate; a gate insulation film covering the gate electrode; an oxide semiconductor layer formed on the gate insulation film; an etching stopper film formed on a channel forming portion of the oxide semiconductor layer, and a source electrode and a drain electrode covering an edge portion of the etching stopper film. The etching stopper film is made of an insulating material, and the insulating material is capable of attenuating a light having wavelength not greater than 450 nm.</p> |
