Document Type and Number:
WIPO Patent Application WO/2015/151312
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical film capable of suppressing blue light from entering the eye of a user when scattered by the optical film, and capable of sufficiently reducing blue light while keeping the transmittance of other light excluding the blue light to a favorable level. The optical film comprises a transparent base-material film, and an adhesive layer formed on the transparent base-material film, the adhesive layer including resin particles and a silicone based adhesive. If an average transmittance of light with wavelength of 700 to 800nm is To (%) and an average transmittance of light with wavelength of 380 to 500nm is Tb (%), To - Tb (%) is five or more, and total light transmittance is 85% or more.
