Each polymer film has a thickness, every two adjacent polymer films are two different materials, and the thicknesses of the polymer films are gradually decreased from two outmost sides of the multilayer reflective sheet to a middle of the multilayer reflective sheet. At least one of the polymer films is a birefringence material layer that conforms to the condition of NX≠NY≠NZ, where NX is the index of refraction of light at X direction of the multilayer reflective sheet, NY is the index of refraction of light at Y direction of the multilayer reflective sheet, and NZ is the index of refraction of light at Z direction of the multilayer reflective sheet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing a reflective optical film","description":"A reflective optical film includes a reflective light-polarizing unit including a multilayer reflective sheet composed of a plurality of polymer films stacked on top of one another.
