Claim 2:
3. An electro-optical device, comprising:
a first substrate;
a second substrate bonded to the first substrate;
a liquid crystal layer provided between the first substrate and the second substrate;
a third substrate provided at a third surface of the first substrate, the third surface being located on a side of the first substrate that is opposite to the liquid crystal layer; and
a frame configured to house the first substrate, the second substrate and the third substrate, wherein
the frame includes an abutment surface directly contacting and abutting on the third surface,
the abutment surface is located between a side surface of the third substrate and a side surface of the first substrate,
the third substrate is smaller than the first substrate, and
side surfaces of the first substrate and the second substrate and an inner wall of the frame are bonded to each other via an adhesive, and a side surface of the third substrate and the first substrate are not joined by the adhesive.
