ANTIGLARE FILM AND DISPLAY DEVICE EMPLOYING THE SAME, AND LIGHT DIFFUSING FILM AND SURFACE LIGHT SOURCE SYSTEM EMPLOYING THE SAME

摘要

An actinic-energy-ray-curable resin composition (10) is supplied to the nip between a roll-shaped die (7) obtained by subjecting the peripheral surface of a roll-shaped metal member to blasting to thereby form a finely roughened structure and a filmy light-transmitting substrate (9) disposed along the peripheral surface of the roll-shaped die (7), thereby forming the actinic-energy-ray-curable resin composition (10) into a thin film. The finely roughened structure in the peripheral surface of the roll-shaped die (7) is transferred to a surface of the thin film. This actinic-energy-ray-curable resin composition (10) is cured to form a light-transmitting thin film. This film is bonded to the surface of the light-transmitting substrate (9) to obtain an antiglare film. That surface of the light-transmitting thin film which has the finely roughened structure has an arithmetic average inclination angle of 0.5-3.5 degrees.
