Abstract
An embodiment of the present invention is an antiglare film which includes an antiglare layer having particles A, particles B, and a binder matrix on a transparent substrate. A difference in refractive index between the particles A and the binder matrix (|n−n|) is 0.060 or less. A difference in refractive index between the particles B and the binder matrix (|n−n|) is in the 0.080-0.300 range. An average diameter (unit: μm) of the particles B (r) is in the 0.5-5.0 μm range. The product value |n−n|wH, which is obtained by multiplying a difference in refractive index between said particles B and said binder matrix (|n−n|) by a content (part by weight) of said particles B as against 100 parts by weight of said binder matrix (w) and an average thickness (unit: μm) of said antiglare layer (H) is in the 10.0-15.0 range.
