Abstract

The present invention aims to provide an antiglare light diffusing member utilizing internal diffusion and surface diffusion in combination, wherein a surface haze value mainly representing the degree of the surface diffusion and an internal haze value mainly representing the degree of the internal diffusion are easily adjusted independently from each other. An antiglare light diffusing member comprising an antiglare light diffusing layer comprising a binder matrix and a particle A and a particle B on a transparent base material, wherein the difference between the refraction index of the particle A and the refraction index of the binder matrix is less than 0.02, and the difference between the refraction index of the particle B and the refraction index of the binder matrix is in the range of 0.03-0.20.

Claims (5)

1. An antiglare light diffusing member comprising an antiglare light diffusing layer comprising a binder matrix and particles A and spherical particles B on a transparent base material, wherein

the difference between the refraction index of any of the particles A and the refraction index of the binder matrix is less than 0.02,

the difference between the refraction index of any of the spherical particles B and the refraction index of the binder matrix is in the range of 0.03-0.20, and

the antiglare light diffusing layer has a surface haze value in the range of 1-15%, and an internal haze value in the range of 15-50%.

2. A display having the antiglare light diffusing member according to claim 1 on the outermost surface thereof.
