PROBLEM TO BE SOLVED: To provide a polarizing laminate which achieves display of a sharp transmission image while maintaining visibility of an image projected from a projector, even when the laminate is used in a translucent screen including a diffusion type polarizing plate.SOLUTION: A polarizing laminate 1 that is transparent and included in a translucent projector screen for displaying an image projected from a projector 4 is obtained by laminating a diffusion type polarizing layer 3 described below and an absorption type polarizing plate 2 with transmission axes of the respective layers being substantially parallel to each other. The diffusion type polarizing layer 3 includes a continuous phase formed of a first transparent thermoplastic resin and a dispersion phase formed of a second transparent thermoplastic resin having a refractive index different from that of the continuous phase. The diffusion type polarizing layer 3 is formed of a stretched sheet, in which the continuous phase has an in-plane birefringence of less than 0.05; the dispersion phase has an in-plane birefringence of 0.05 or more; and the difference between the refractive indices of the continuous phase and the dispersion phase with respect to linearly polarized light in the stretching direction may be different from the difference between the refractive indices in a direction perpendicular to the stretching direction. |
