A multilayer laminated film and a projected image display member are provided that are capable of reducing a luminance difference in an image due to a difference in projection angle when used in a projection member of an augmented reality device or the like, where the multilayer laminated film is obtained by alternately laminating 51 layers or more of a plurality of different thermoplastic resin layers, in which a transmittance of visible light perpendicularly incident on a surface of the multilayer laminated film is 50% or more and 100% or less, and when average reflectances of P-polarized wave at the time of visible light being incident on the surface of the multilayer laminated film are denoted as Rp20 (%), Rp30 (%), Rp40 (%), Rp50 (%), Rp60 (%), and Rp70 (%).
