Abstract:
1. An antiglare light diffusing member comprising: a transparent base material; and an antiglare light diffusing layer including a binder matrix, a plurality of first particles (A) and a plurality of second particles (B), wherein a front surface of the layer is irregular; wherein difference between a refractive index of the plurality of first particles (A) and a refractive index of the binder matrix is less than or equal to 0.02 and difference between a refractive index of the plurality of second particles (B) and a refractive index of the binder matrix is 0.03-0.20, wherein an average particle diameter of the plurality of first particles (A) is bigger than an average film thickness of the antiglare light diffusing layer and is smaller than 1.4 times of an average film thickness of the antiglare light diffusing layer, and an average particle diameter of the plurality of particles (B) is smaller than 0.9 times of the average film thickness of the antiglare light diffusing layer and wherein content of the plurality of first particles (A) is 1.0-4.5 wt % in the antiglare light diffusing layer and content of the plurality of second particles (B) is 0.5-4.0 wt % in the antiglare light diffusing layer.
