An electrooptic device includes a first substrate 10, wiring 16 provided along one side of the first substrate 10 to extend to another side crossing the one side, and a coating layer 30 coating the wiring 16. Conceivable examples of the electrooptic device include a liquid crystal device, and an EL device. In the liquid crystal device, the coating layer 30 can be formed by a sealing material for bonding together the first substrate 10 and a second substrate 20 opposed to each other. The wiring 16 is coated with the coating layer 30 to be cut off from contact with the outside air.
