    摘要: 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.

    摘要: 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.
