Optical film, display device using the same, composition for forming ultraviolet absorbing layer used for producing optical film

Abstract

Provided are an optical film that can reduce reflectance, increase luminance, and reduce thickness of a display device, a display device using the optical film, and a composition for forming ultraviolet absorbing layer used for producing the optical film. An optical film characterized in that having a transparent substrate, a colored layer laminated on one side of the transparent substrate and containing a dye, and a functional layer laminated on the colored layer, in which the dye contains a first coloring material having a maximum absorption wavelength within the range of 470 to 530 nm, and a second coloring material having a maximum absorption wavelength in the range of 560 to 620 nm, and the functional layer includes an ultraviolet absorbing layer having an ultraviolet shielding rate of 85% or more, and the pencil hardness of the surface under a load of 500 g is H or higher.
