Electrical device

An electrical device comprising:

• a first substrate having a first side and a second side, the first side being opposed to the second side;
• a second substrate opposed to the first side of the first substrate;
• a functional element arranged 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, the first electrode overlapping with the functional element in a planar view;
• a second electrode arranged to a second substrate side of the functional element, the second electrode overlapping with the functional element in the planar view;
• an electronic circuit arranged between the functional element and the first electrode, the electronic circuit overlapping with the first electrode and the second electrode in the planar view, the electronic circuit driving the functional element;
• and
• a connecting section electrically connecting the first electrode to the second electrode;
• a protection circuit coupled between an output terminal of the electronic circuit and the first electrode;
• a first wiring arranged between the first electrode and the functional element, a first potential being applied to the first wiring;
• and
• a second wiring arranged between the first electrode and the functional element, a second potential, which is different from the first potential, being applied to the second wiring,
• wherein the protection circuit comprises a first electrostatic protection circuit coupled between the output terminal and the first wiring, and a second electrostatic protection circuit coupled between the output terminal and the second wiring.
