PROBLEM TO BE SOLVED: To provide a diffusion lens sheet laminate which is very lightweight and low in cost and free from the generation of unevenness in brightness even when it is used for a long period of time, and has both of high total light transmittance and high haze rate.SOLUTION: The diffusion lens sheet laminate has a diffusion sheet and a lens film laminated through an air layer. The diffusion sheet contains cellulose, and has a basis weight of ≤300g/m, a haze rate of ≥80%, as measured by a single method of JIS K7105, and a total light transmittance of ≥70%. The distance between the reference surfaces of the diffusion sheet and the lens film is 700 nm to 10 mm. |
