Abstract

In one embodiment, an electrical device includes a first substrate with a first side and a second side, a second substrate opposed to the first side of the first substrate, and a functional element between the first side of the first substrate and the second substrate. A first electrode arranged to a first substrate side of the functional element and overlaps with the functional element in planar view. A second electrode is arranged to a second substrate side of the functional element and overlaps with the functional element in planar view. An electronic component is arranged between the functional element and the first electrode, overlaps with the first electrode and the second electrode in planar view, and drives the functional element. A connecting section electrically connects the first electrode to the second electrode and a protection circuit between an output terminal of the electronic circuit and the first electrode.
