A wide-viewing-angle lenticular lens sheet and a production method therefore. The lenticular lens sheet () comprises a plurality of lenticular lenses () disposed on one surface of a translucent substrate, and convex lenses () disposed on the other surface of the translucent substrate each at a condensing position to which light from a lenticular lens () is condensed. External light absorbing units each consisting of only slant surfaces () are disposed on the other surface of the translucent substrate at positions different from those of the lenses ().

Lenticular lens sheet and production method therefor

Provided is a lenticular lens sheet on which external light reflection is greatly reduced and which gives high-contrast sharp images. The lenticular lens sheet has a plurality of lenticular lenses formed on one surface of a light-transmissive substrate and having, on the other surface of the substrate, convex lenses , and external light-absorbing ridges as formed alternately with those convex lenses and coated with an external light-absorbing layer on their tops, in which every furrow between each convex lens and each external light-absorbing ridge that ate adjacent to each other is further coated with an external light-absorbing layer . The external light-absorbing layer may be not only on the top of each ridge but also around each ridge adjacent to the top thereof.
