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.

A diffusion sheet includes: a substrate having a first principal surface and a second principal surface; and structures each in a convex shape formed randomly on the first principal surface or the second principal surface of the substrate. The structures have an identical or almost identical height. The structures have an aspect ratio h/r, where r denotes an average radius of the structures and h denotes an average height of the structures, of more than 0.85 and not more than 1.50. The structures have a filling factor of not less than 60% and not more than 80%.

An illumination apparatus is disclosed. The illumination apparatus includes a polarization plate, a light source, and a light transmission film. The light transmission film is disposed between the polarization plate and the light source and includes a plurality of prisms formed on a surface thereof, the plurality of prisms each having a ridge line in a first direction and being continuously arranged in a second direction perpendicular to the first direction. In the illumination apparatus, the light transmission film is disposed such that a ridge line direction of the plurality of prisms is one of a perpendicular direction and an approximately perpendicular direction to a transmission axis of the polarization plate.

A light-transmissive film for use in display devices is provided. The light-transmissive film includes a plurality of first protrusions formed on one surface and extending in a predetermined direction of the one surface, and a plurality of second protrusions formed on an opposite surface to the one surface, extending in one direction of the opposite surface, arranged parallel to the one direction, and arranged parallel to a direction intersecting the one direction. At least one of the first and second protrusions has a refractive index anisotropy in a plane.

A light-transmitting film that has a predetermined polarization split function, in addition to a light-collecting function is provided. The index of refraction nx in a prism extension direction and the index of refraction in a prism alignment direction differ from each other. By generating a difference in the indices of refraction in the prism extension direction and the prism alignment direction orthogonal thereto, for the light incident on the light-transmitting film, the polarization component Lx oscillating in the prism extension direction and the polarization component Ly oscillating in the prism alignment direction can have different transmission characteristics. For example, by setting the index of refraction in the prism extension direction greater than the index of refraction in the prism alignment direction (nx>ny), among the light incident on the light-transmitting film, the amount of return light of the polarization component Lx oscillating in the prism extension direction is greater than that of the polarization component Ly oscillating in the prism alignment direction. In this way, not only a light-collecting function, but also a predetermined polarization split function is obtained.
