LENTICULAR LENS SHEET AND PROCESS FOR PRODUCTION THEREOF, AND OPTICAL ELEMENT

摘要

Disclosed are: a lenticular lens sheet which can be used in a three-dimensional display, a rear projection display, a projection screen and the like; and a means for producing the lenticular lens sheet at low cost without the need of using any mold. The lenticular lens sheet comprises at least a transparent support substrate, multiple lenticular lenses, and septa each placed between adjacent two of the multiple lenticular lenses, and is produced by applying a transparent resin composition ink onto regions surrounded by the septa in an ink-jet mode and curing the transparent resin composition ink with an ultraviolet ray.
