Abstract
In an electro-optical device, a first substrate is provided with a temperature detection element and an electro-static protection circuit that protects the temperature detection element from a surge current. A first resistor element is electrically coupled to the temperature detection element in series. The electro-static protection circuit includes a transistor electrically coupled to the first resistor element and the temperature detection element in parallel. A first capacitance element is provided on a wiring substrate electrically coupled to the first substrate, and is provided between a first coupling wiring line electrically coupled to one side of the temperature detection element and a second coupling wiring line electrically coupled to the other side thereof.
