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/cm3 or less. The quotient value (RA/H), which is obtained by division of the average diameter of the particles A (RA) by the average thickness of the antiglare layer (H), is in the 0.40-0.80 range. The quotient value (RB/RA), which is obtained by division of the average diameter of the particles B (RB) by the average diameter of the particles A (RA), is in the 0.20-0.60 range. The quotient value ((wA+wB)/wM), which is obtained by dividing the sum of the content of the particles A (wA) and that of the particles B (wB) in the antiglare layer (wA+wB) by the content of the binder matrix in the antiglare layer (wM), is in the 0.10-0.40 range. The quotient value (wB/wA), which is obtained by division of the content of the particles B (wB) by that of the particles A (wA) in the antiglare layer, is in the 0.50-1.50 range.
