Provided is a polarizing laminate capable of displaying a clear transmitted image while maintaining the visibility of an image projected from a projector, even if it is a translucent screen including a diffusive polarizing plate. As a polarizing laminate 1 that is transparent and included in a translucent projector screen for displaying an image projected from a projector 4, a continuous phase formed of a first transparent thermoplastic resin, and this A diffusion-type polarizing layer 3 including a disperse phase formed of a second transparent thermoplastic resin having a refractive index different from that of the continuous phase and an absorption-type polarizing layer 2 are laminated so that the transmission axes of both layers are substantially parallel. To do. The diffusive polarizing layer 3 is formed of a stretched sheet, the in-plane birefringence of the continuous phase is less than 0.05, the in-plane birefringence of the dispersed phase is 0.05 or more, and a continuous phase for linearly polarized light And the refractive index difference between the dispersed phase may be different between the stretching direction and the direction perpendicular to the stretching direction.
