Publication number: 20090073566Abstract: In a manufacturing method of the present invention, a diffusion sheet having a flat size of a product size or more is laminated to a front surface and/or back surface of a lens sheet having flat size of the product size or more, and the stack is cut along its periphery into the product size, and the lens sheet and the diffusion sheet are bonded to each other at least one or more peripheral points thereof. This eliminates a step for individually cutting a number of films (sheets) into a product size, and a step for aligning the number of films (sheets) for lamination. In addition, the method does not cause a problem of waste of protective sheets, but provides advantages in both cost and quality. There is no problem caused in laminating a number of films, or problems caused by different thermal expansions/thermal shrinkages of a plurality of films.Type: ApplicationFiled: August 29, 2006Publication date: March 19, 2009Applicant: FUJIFILM CORPORATIONInventors: Ryuichi Katsumoto, Hideo Nagano, Keisuke Endo, Yoshisada Nakamura, Akihiko Takeda
