Abstract
An antiglare film includes an antiglare layer having a binder matrix, and particles A and particles B therein on a transparent substrate. A difference in density between the particles A and particles B is 0.2 g/cmor less. The quotient value (R/H), which is obtained by division of the average diameter of the particles A (R) by the average thickness of the antiglare layer (H), is in the 0.40-0.80 range. The quotient value (R/R), which is obtained by division of the average diameter of the particles B (R) by the average diameter of the particles A (R), is in the 0.20-0.60 range. The quotient value ((w+w)/w), which is obtained by dividing the sum of the content of the particles A (w) and that of the particles B (w) in the antiglare layer (w+w) by the content of the binder matrix in the antiglare layer (w), is in the 0.10-0.40 range. The quotient value (w/w), which is obtained by division of the content of the particles B (w) by that of the particles A (w) in the antiglare layer, is in the 0.50-1.50 range.
