Abstract
A lens film with small warpage even when a transparent base is thin is provided. Pole prisms made of a hardening resin are arranged along the extending direction on a transparent base made of a flexible material. The transparent base has a depression according to a valley between the pole prisms adjacent to each other. The pole prism has a sloping face extending to an inner wall of the depression. The transparent base is in contact with the valley. A layer not functioning as a prism, that is, a so-called skirt layer does not exist between the transparent base and the pole prisms.
