ABSTRACT:
A reflective type screen comprising a reflective surface layer a polarizing plate layer located in front of said reflective surface layer and a diffusion layer located in front of the polarized plate layer, wherein the reflective surface layer, the polarizing plate layer and the diffusion layer are laminated together using an adhesive to form an integral structure is disclosed. In addition, a reflective type screen comprising a reflective surface layer subjected to mirror-surface processing and laid on a flexible substrate, a polarizer and a diffusion layer arranged for covering the polarizer therewith wherein the reflective surface layer, the polarizer and the diffusion layer are laminated together using an adhesive to form an integral structure is disclosed. Additionally, a reflective type screen comprising a polarizer a protective layer located in front of the polarizer for protecting the polarizer and adhesively secured to the polarizer, a surface of the protective layer located on the incident side being subjected to diffusion processing, and another protective layer located behind the polarizer for protecting the polarizer and adhesively secured to the polarizer, a surface of the protective layer located on the incident side being subjected to mirror-surface processing, wherein the polarizer, the protective layer and the another protective layer are laminated together using an adhesive to form an integral structure is disclosed.
