METHOD FOR PRODUCING LENTICULAR LENS, LENTICULAR LENS, OPTICAL ELEMENT AND THREE-DIMENSIONAL DISPLAY DEVICE

摘要

Provided is a method for manufacturing a lenticular lens sheet to be used in a stereoscopic display, a projection screen, and the like without using a mold at low cost. A method of manufacturing a lenticular lens sheet, the lenticular lens sheet including a support substrate and a plurality of lenticular lenses formed on the support substrate, includes the steps of: (1) filling a transparent resin composition ink containing an ultraviolet-curable component of 90 wt % or more and having surface ink-repellency after curing with ultraviolet light to a lens area of an even-numbered array by an inkjet method; (2) curing the transparent resin composition ink obtained in the step (1) with ultraviolet light; (3) filling a transparent resin composition ink containing the ultraviolet-curable component of 90 wt % or more and being curable with ultraviolet light to a lens area of an odd-numbered array by an inkjet method; and (4) forming the plurality of lenticular lenses in the lens areas of the even-numbered array and the odd-numbered array by curing the transparent resin composition ink obtained in the step (1) and the transparent resin composition ink obtained in the step (3) with ultraviolet light.
