  • Patent number: 8936837
    Abstract: The method includes: forming a coating film including particles and an ultraviolet curable resin on a film substrate; and curing the ultraviolet curable resin by ultraviolet irradiation to form an anti-glare layer constituted by the particles and the ultraviolet curable resin. A ratio of a thickness A of the anti-glare layer to a diameter B of the particles is in the range of 1.5 to 2.4. The ultraviolet irradiation is performed with two or more ultraviolet irradiation units, the first unit irradiation amount is 49 mJ/cm2 or less, the second and subsequent units irradiation amount is greater than 50 mJ/cm2, and the total irradiation amount is 100 mJ/cm2 or greater. The oxygen concentration at a position which is 1 mm above a surface of the coating film is 1 ppm to 2000 ppm.
