Patent ID: 7182877

Claim:
A method for manufacturing an electro-optical device including: a first substrate; a second substrate bonded opposite the first substrate by a sealing material provided therebetween, the second substrate including a protruding region; wiring lines and terminals located within the protruding region; and wiring positioned within a gap between the first substrate and the second substrate, the method comprising: covering all of the wiring lines and terminals formed within the protruding region of the second substrate with a protective layer, at least the edges and cut faces of the first substrate and the second substrate being free of the protection layer; and etching at least edges and cut faces of the first substrate and the second substrate to remove scratches from the first substrate and the second substrate while the wiring lines and terminals are in a covered state and at least the edges and cut faces of the first substrate and the second substrate are free of the protection layer.
