An optical sheet is provided. The optical sheet includes: a light-transmissive base; and an optical functional layer provided to at least one surface of the base, in which the base is composed of a stack of transmissive sheets bonded while placing an adhesive material layer in between.

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.

Method for producing an optical sheet

An optical packaged body capable of preventing generation of a wrinkle, deflection, and warpage, and capable of being thinned is provided. The optical packaged body includes a support medium and a packaging film that covers the support medium in a state of being applied with shrinkage force. The packaging film has an optical function section that acts on light from a light source in at least one of a first region into which the light from the light source enters and a second region from which the light from the light source is emitted after passing through the optical packaged body when the light source is arranged on one face side of the optical packaged body.
