Abstract: The laminate film is a laminate including 51 or more layers in which an A layer mainly composed of a thermoplastic resin A and a B layer mainly composed of a thermoplastic resin B, which is different from the thermoplastic resin A, are alternately laminated. A transmission spectrum X is obtained by exposing the film to linear polarized light (X wave) that oscillates in the alignment direction of the film over a range of wavelengths from 300 to 900 nm. A transmission spectrum Y is obtained by exposing the film to linear polarized light (Y wave) that oscillates in the direction perpendicular to the alignment direction of the film over a range of wavelengths from 300 to 900 nm. The area Amax (nm·%) of the largest region among regions enclosed by the transmission spectrum X and the transmission spectrum Y is 150 to 1500.
