Patent ID: 7589897

Claim:
An antiglare film, comprising: a transparent substrate; and an antiglare layer on the transparent substrate, the layer including a binder matrix, organic particles (A) and organic particles (B) having an average particle diameter smaller than an average particle diameter of particles (A), organic particles (A) and organic particles (B) being dispersed in the binder matrix, wherein a value (R A /H), which is the average particle diameter (R A ) of organic particles (A) divided by the average film thickness (H) of the antiglare layer, is equal to or more than 0.40 and equal to or less than 0.80; wherein a value (R B /R A ), which is the average particle diameter (R B ) of organic particles (B) divided by the average particle diameter (R A ) of organic particles (A), is equal to or more than 0.20 and equal to or less than 0.60; wherein a value ((W A +W B )/W M ), which is the total of the content (W A ) of organic particles (A) and the content (W B ) of organic particles (B) in the antiglare layer divided by the content (W M ) of a binder matrix in an antiglare layer, is equal to or more than 0.10 and equal to or less than 0.40; wherein a value (W B /W A ), which is the content (W B ) of organic particles (B) in the antiglare layer divided by the content (W A ) of organic particles (A) in the antiglare layer, is equal to or more than 0.50 and equal to or less than 1.50; wherein the difference in refractive index (|n A −n M |) between the refractive index (n A ) of organic particles (A) and the refractive index (n M ) of the binder matrix is equal to or more than 0.02 and equal to or less than 0.05, and the difference in refractive index (|n B −n M |) between the refractive index (n B ) of organic particles (B) and the refractive index (n M ) of the binder matrix is equal to or more than 0.02 and equal to or less than 0.05; and wherein the difference in refractive index (|n A −n B |) between the refractive index (n A ) of organic particles (A) and the refractive index (n B ) of organic particles (B) is equal to or less than 0.01.
