  • Electro-optical device, image printing apparatus, and method of manufacturing electro-optical device
    Patent number: 7660022
    Abstract: 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; and a converging lens array which has a plurality of distributed index lenses, each transmitting light traveling from 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. The electro-optical panel is directly bonded to the converging lens array.
    Type: Grant
