Patent ID: 8199296

Claim:
An antiglare film comprising: a transparent substrate; and an antiglare layer including particles A1, particles A2, particles B, and a binder matrix on said transparent substrate, wherein a difference in refractive index between said particles A1 (n M ) and said binder matrix (n M ) is 0.060 or less, wherein a difference in refractive index between said particles A2 (n A2 ) and said binder matrix (n M ) is 0.060 or less, wherein a difference in refractive index between said particles B (n B ) and said binder matrix (n M ) is in the 0.080-0.300 range, wherein an average diameter of said particles B (r B ) is in the 0.5-5.0 μm range, wherein a value (|n A1 -n M |w A1 +|n A2 -n M w A2 +|n B -n M |w B )H, which is a product obtained by multiplying H, an average thickness of said antiglare layer by a sum of |n A1 -n M |w A1 , a product of multiplication of a difference in refractive index between said particles A1 and said binder matrix by a content (unit: part by weight) of said particles A1 in said antiglare layer with respect to 100 parts by weight of said binder matrix, |n A2 -n M |w A2 , a product of multiplication of a difference in refractive index between said particles A2 and said binder matrix by a content (unit: part by weight) of said particles A2 in said antiglare layer with respect to 100 parts by weight of said binder matrix, and n B -n M |w B , a product of multiplication of a difference in refractive index between said particles B and said binder matrix by a content (unit: part by weight) of said particles B in said antiglare layer with respect to 100 parts by weight of said binder matrix, is in the 2.0-30.0 range, and wherein r A1 /H, a quotient value of an average diameter of said particles A1 (r A1 ) by an average thickness of said antiglare layer (H), is in the 0.20-0.80 range if said particles A1 have a larger average diameter than said particles A2.
