Abstract
The purpose is to provide an antiglare light diffusing member that can satisfy both of external light reflection preventiveness and good contrast when being used for a display. The antiglare light diffusing member is made to be an antiglare light diffusing member having an antiglare light diffusing layer including a binder matrix and particles on a transparent base material, wherein the two types of arithmetical mean roughness (Ra, Ra) of the antiglare light diffusing layer defined by JIS-B0601-1994 are in the following range: Rais in the range of 0.008-0.020 μm when cutoff wavelength λc is 0.008 mm; and Rais less than 0.200 μm when cutoff wavelength λc is 0.8 mm.
