本发明提供一种防炫膜，其系即使为低雾度在广观察角度中仍具有优异之防炫性，且配置于图像显示装置时，可充分抑制白化及炫光之发生。;本发明更提供一种防炫膜，其系具备透明支撑体、与形成于该透明支撑体上之具有细微表面凹凸形状之防炫层，全雾度为0.1%以上且3%以下，表面雾度为0.1%以上且2%以下，相对于以入射角30°入射之光，反射角30°之反射率R(30)与反射角40°之反射率R(40)之比R(40)/R(30)为0.00001以上且0.0025以下，上述表面凹凸形状之标高之功率谱之在空间频率0.01μm -1 、空间频率0.02μm -1 及空间频率0.1μm -1 中之强度I(0.01)、I(0.02)及I(0.1)分别在预定范围内。;The antiglare film contains a transparent supporting member and an antiglare layer formed on the transparent supporting member, the antiglare layer having a surface with fine undulations, a total haze of 0.1% or more to3% or less, a surface haze of 0.1% or more to 2% or less, and a ratio of reflectivity R (40) / R (30) of 0.00001 or higher to 0.0025 or less with respect to incident light at 30 degrees, wherein R (40) demotes a reflectivity at 40 degrees and R (30) denotes a reflectivity at 30 degrees. The abovesaid surface undulations have an intensity of the power spectrum of I(0.01), I(0.02) and I(0.1) or space frequency 0.01 μm -1 at space frequency0.02 μm -1 and space frequency 0.1 μm -1 at a set elevation of the abovesaid surface undulations within the respective predetermined range. |
