Abstract

The present invention provides a laminate film and a display member including the laminate film, which are excellent in visibility of external information such as scenery and displayability of information from a projection member, and are also excellent in color tone reproducibility. The laminate film includes a laminate of 50 or more alternately arranged layers of a plurality of different thermoplastic resins, the laminate film having a transmittance of light incident perpendicularly to a film surface of 50% or more, the laminate film satisfying a relationship of R20≤R40<R70, wherein R20, R40, and R70 are reflectances of a P-wave incident at angles of 20°, 40°, and 70°, respectively, to the normal to the film surface, the reflectance of R70 being 30% or more, reflected light of the P-wave incident at 70° to the normal to the film surface having a saturation of 20 or less.
