PROBLEM TO BE SOLVED: To provide a cohesive film for protection of an optical sheet before inspection which is excellent in the protecting performance for an optical sheet before inspection, permit highly accurate inspection of defects in the optical sheet before inspection while the cohesive film is stuck thereto and when an adhesive, a hard coating agent or the like is applied on the surface of the optical sheet after the cohesive film is removed, shows the good appearance of the coating, and to provide the optical sheet with the protective film before inspection and a method for manufacturing the optical sheet by using the above film. SOLUTION: The cohesive film for protection of an optical sheet before inspection prepared by forming a cohesive layer on one surface of a plastic film, has a transmittance of >=80% for all rays and has a removable contamination preventing layer laminated on the back face of the cohesive film. |
