Abstract: An array substrate includes a first TFT that includes a first insulation film, a first semiconductor film in a layer upper than the first insulation film, a second insulation film in a layer upper than the first semiconductor film, a first gate electrode in a layer upper than the second insulation film and overlapping the first semiconductor film, a third insulation film in a layer upper than the first gate electrode, a first source electrode and a first drain electrode that are portions of a metal film in a layer upper than the third insulation film and connected to the first semiconductor film via first contact holes in the third insulation film, and an auxiliary film made of non-metal material and in a layer upper or lower than the first semiconductor film to overlap at least lower surfaces of the first source electrode and the first drain electrode.
