Definitions

  • a light diffusion film laminate for a reflective display device which has excellent reflective luminance and hardly produces an interference rainbow, and a reflective display device using the same.
  • the light diffusion film laminate A includes at least an anisotropic light diffusion layer 100 and an isotropic light diffusion layer 200 provided on at least one side of the anisotropic light diffusion layer 100 (see FIG. 3).
  • the average value of the short diameters SA of the plurality of columnar structures 123 (average short diameter of the columnar structures 123) is preferably 0.5 ⁇ m or more, more preferably 0.7 ⁇ m or more, and even more preferably 1.0 ⁇ m or more.
  • the average value (average minor axis) of the short diameters SA of the plurality of columnar structures 123 is preferably 5.0 ⁇ m or less, more preferably 4.0 ⁇ m or less, and even more preferably 3.0 ⁇ m or less.
  • the lower limit value and upper limit value of the average minor axis of the plurality of columnar structures 123 can be appropriately combined.
  • fine particles that can be mixed or dispersed in the base material are not particularly limited as long as they have a different refractive index from the base material.
  • the difference between the refractive index of the base material (method B according to JIS K-7142) and the refractive index of the fine particles is preferably in the range of 0.01 to 0.50, more preferably in the range of 0.02 to 0.20.
