An electro-optical device includes an electro-optical panel which has a plurality of electro-optical elements whose light-emitting characteristics or transmissive characteristics are changed by electrical energy applied; a converging lens array which has a plurality of distributed index lenses, each transmitting light traveling in the electro-optical panel to form an erect image with respect to an image on the electro-optical panel, the images formed by the plurality of distributed index lenses constituting a continuous image; and a transmissive spacer unit which is provided between the electro-optical panel and the converging lens array so as to be bonded to them. The spacer unit includes a laminated structure of a plurality of transmissive spacer members.
