Anti glare film, design method of anti glare film, manufacturing method of anti glare film, optical member and image display device

摘要

Problem to be solved: to provide an anti glare film difficult to change the haze value.An anti glare film 10 in which an anti glare layer 12 is laminated on a light transmitting substrate 11.Anti glare layer 12Anti glare layer resin (B1) 12a andContains at least one type of haze adjustment filler (B2) 12bThe haze adjustment filler (B2) 12b isIt is a filler consisting of a copolymer of PST (polystyrene) and PMMA (poly (methyl methacrylate)).The peak area ratio of PMMA peak / PSt peak was higher than 0.51 due to Raman spectroscopy of the HB adjustmentPeak areaThe peak area is calculated as the boundary between the adjacent peaks.The total haze value of the anti glare film 10 ranges from 5 to 45%.Diagram
