Abstract
The display device having a thin film transistor formed on a substrate including a display portion is provided. The thin film transistor including: a gate electrode; a gate insulating film formed so as to cover the gate electrode; a semiconductor laminated film formed on top the gate insulating film so as to extend over the gate electrode, the semiconductor laminated film being formed by laminating at least a polycrystalline semiconductor film and an amorphous semiconductor film, a first electrode and a second electrode disposed on top of the semiconductor laminated film so as to be opposed to each other across a region superposing the gate electrode. In the display device, the semiconductor laminated film is formed immediately below a wiring extending from the first electrode and immediately below a wiring extending from the second electrode.
