ABSTRACT:
A method for manufacturing a hologram optical substrate having a hologram element includes: a cutting process that employs a laminate sheet having a pair of protective sheets with a hologram photosensitive sheet peelably interposed therebetween, and makes a cut to a depth for cutting the hologram photosensitive sheet, the cut corresponding to a hologram element forming section; a first peeling process that peels the protective sheet having the cut; a sticking process that sticks a hologram photosensitive material of the hologram element forming section to an inclined surface of the optical substrate, with the hologram photosensitive material adhered to the other protective sheet; a second peeling process that peels the other protective sheet; an exposure process that exposes the hologram photosensitive material to a laser beam after the second peeling process; and a developing process that develops the exposed hologram photosensitive material so as to form a hologram element.
