Hybrid composition, film using the hybrid composition, optical components and image display device

Abstract

This invention provides a mixed composition that increases the refractive index difference between regions with different refractive indices when formed on a film having regions with different refractive indices in-plane; a film using the mixed composition; an optical component; and an image display device. The mixed composition comprises: a photopolymerizable aliphatic monomer having a refractive index of less than 1.50 at the wavelength of a sodium D line at 25°C; and a polymer having a refractive index of 1.60 or more at the wavelength of a sodium D line at 25°C. The photopolymerizable aliphatic monomer can be blended in a ratio of 40 parts by mass to 300 parts by mass relative to 100 parts by mass of the polymer. The photopolymerizability of each molecule of the photopolymerizable aliphatic monomer can be 4 or less.
