Zusammenfassung:	To provide an anisotropic light diffusion film laminate having a better visual angle dependency improvement effect than before regarding luminance and a color change depending on a viewing angle.SOLUTION: In an anisotropic light diffusion film laminate having at least two-layer anisotropic light diffusion films (a first anisotropic light diffusion film (a) and a second anisotropic light diffusion film (b)), a scattering center axis angle θa of the anisotropic light diffusion film (a) ranges from 10° to 50°, a scattering center axis angle θb of the anisotropic light diffusion film (b) ranges from 30°to 60°, and the maximum linear transmissivity of the anisotropic light diffusion film (a) and the anisotropic light diffusion film (b) is 40% or less each, and the minimum linear transmissivity is 20% or less each.SELECTED DRAWING: Figure 7 【課題】視野角による輝度と色変化に関して、従来よりも優れた視角依存性改善効果を有する異方性光拡散フィルム積層体を提供する。【解決手段】２層の異方性光拡散フィルム（第１の異方性光拡散フィルムａおよび第２の異方性光拡散フィルムｂ）を少なくとも有する異方性光拡散フィルム積層体であって、異方性光拡散フィルムａの散乱中心軸角度θａが、１０°〜５０°であり、かつ、異方性光拡散フィルムｂの散乱中心軸角度θｂが、３０°〜６０°であり、異方性光拡散フィルムａ及び異方性光拡散フィルムｂは、最大直線透過率が、共に４０％以下であり、かつ、最小直線透過率が、共に２０％以下である、異方性光拡散フィルム積層体。【選択図】図７
