The present invention provides a transparent inorganic oxide dispersion which makes it possible to improve the refractive index and mechanical characteristics and to maintain transparency by modifying the surface of inorganic oxide particles with a surface modifier having one or more reactive functional groups; and an inorganic oxide particle-containing resin composition in which the transparent inorganic oxide dispersion and a resin are compositely integrated by the polymerization reaction, a composition for sealing a light emitting element, a light emitting element, and a method for producing an inorganic oxide particle-containing resin composition; and a hard coat film which has high transparency and makes it possible to improve a refractive index and tenacity, an optical functional film, an optical lens and an optical component. The transparent inorganic oxide dispersion of the present invention comprises inorganic oxide particles which have a surface modified with a surface modifier having one or more reactive functional groups and have a disperse particle diameter of 1 nm or more and 20 nm or less, and a disperse medium, wherein the surface modifier is one or more kinds selected from the group consisting of a silane coupling agent, a modified silicone, and a surfactant.

The transparent conductive film of the present invention is formed to have a conductive layer containing at least ruthenium fine particles, gold fine particles and silver fine particles, the weight ratio of ruthenium fine particles and gold fine particles in the conductive layer being within the range of 40:60 to 99:1. As a result, this transparent conductive film and a display device having this transparent conductive film have superior electromagnetic wave shielding effects and anti-reflection effects, high chemical stability and superior visibility.
