PROBLEM TO BE SOLVED: To accurately form a light-shielding pattern on the lower surface of a lens sheet, by uniformly and stably forming the fine pattern of an adhesive part and a non-adhesive part on a photosensitive adhesive layer. SOLUTION: The method for forming the light-shielding pattern on the lens sheet includes a step for successively arranging the photosensitive adhesive layer 15 and support base material 14, having an ultraviolet absorbing function on one side of a transparent sheet 12 on the other side of which a lenticular lens 11 is formed; a step for forming the pattern of the adhesive part 15b and the non-adhesive part 15a on the photosensitive adhesive layer, corresponding to the light-condensing part and the light non-condensing part of the photosensitive adhesive layer 15 by irradiating the photosensitive adhesive layer 15 with an exposure source (ultraviolet rays) from the other side of the transparent sheet 12; and a step for transferring a light-shielding layer 17 to the adhesive part 15b of the photosensitive adhesive layer 14. By this method, irradiating light transmitted through the photosensitive adhesive layer 15 is absorbed by the support base material 14, and re-incidence due to the reflected light on the back surface of the supporting base material 14 on the periphery of the light condensing part is prevented, and the fine adhesive pattern, obtained by exposing only the light-condensing part, is formed.
