Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A reflective type screen comprising; a reflective surface layer to which an incident light containing a polarized light is irradiated and from which the reflected light having the same polarization direction as that of said incident light is irradiated to build a projected image, a polarizing plate layer located in front of said reflective surface layer and having a permeation axis extending in the same direction as the polarization direction of said incident light, and a diffusion layer located in front of said polarizing plate layer wherein said reflective surface layer, said polarizing plate layer and said diffusion layer are laminated together to form an integral structure.
Claim 2
Dependent Claim
107 words
A reflective type screen comprising; a reflective surface layer to which an incident light containing a polarized light is irradiated and from which the reflected light having the same polarization direction as that of said incident light is irradiated to build a projected image, a polarizing plate layer located in front of said reflective surface layer and having a permeation axis extending in the same direction as the polarization direction of said incident light, and a diffusion layer located in front of said polarizing plate layer wherein said reflective surface layer, said polarizing plate layer and said diffusion layer are laminated together to form an integral structure.
Claim 3
Dependent Claim
28 words
The reflective type screen as claimed in claim 1, wherein said polarizing plate layer is composed of two layers of polarizing plates each having a same permeation axis.
Claim 4
Dependent Claim
82 words
A reflective type screen comprising; a reflective surface layer subjected to mirror-surface processing and laid on a flexible substrate, a polarizer having a permeation axis extending in the same direction as the polarization direction of an incident light containing a polarized light, said incident light being reflected therefrom to build a projected image, and a diffusion layer arranged for covering said polarizer therewith wherein said reflective surface layer, said polarizer and said diffusion layer are laminated together to form an integral structure.
Claim 5
Dependent Claim
82 words
A reflective type screen comprising; a reflective surface layer subjected to mirror-surface processing and laid on a flexible substrate, a polarizer having a permeation axis extending in the same direction as the polarization direction of an incident light containing a polarized light, said incident light being reflected therefrom to build a projected image, and a diffusion layer arranged for covering said polarizer therewith wherein said reflective surface layer, said polarizer and said diffusion layer are laminated together to form an integral structure.
Claim 6
Dependent Claim
128 words
A reflective type screen comprising; a polarizer having a permeation axis extending in the same direction as the polarization direction of an incident light containing a polarized light, said incident light being reflected therefrom to build a projected image, a protective layer located in front of said polarizer for protecting said polarizer and adhesively secured to said polarizer, a surface of said protective layer located on the incident side being subjected to diffusion processing, and another protective layer located behind said polarizer for protecting said polarizer and adhesively secured to said polarizer, a surface of said another protective layer located on the incident side being subjected to mirror-surface processing wherein said polarizer, said protective layer and said another protective layer are laminated together to form an integral structure.
Claim 7
Dependent Claim
128 words
A reflective type screen comprising; a polarizer having a permeation axis extending in the same direction as the polarization direction of an incident light containing a polarized light, said incident light being reflected therefrom to build a projected image, a protective layer located in front of said polarizer for protecting said polarizer and adhesively secured to said polarizer, a surface of said protective layer located on the incident side being subjected to diffusion processing, and another protective layer located behind said polarizer for protecting said polarizer and adhesively secured to said polarizer, a surface of said another protective layer located on the incident side being subjected to mirror-surface processing wherein said polarizer, said protective layer and said another protective layer are laminated together to form an integral structure.
