Abstract
The invention provides a fine particle dispersion composition that does not depend on a curing method and that has adaptability to the curing methods and versatility and can provide a highly transparent optical component, an optical component using the fine particle dispersion composition and a method of manufacturing the same, and an optical film laminate using the optical component, and also provides a polarization splitting device using the optical component. In order to achieve the above, there is provided an optical component, which is obtained by curing a fine particle dispersion composition, which comprises metal-oxide fine particles, an organic resin material adapted to cure by absorbing energy, one of a polyoxyethylene alkyl ether phosphoric acid-based surfactant and a polyoxyethylene alkyl ether carboxylic acid-based surfactant, each of which has a molecular weight of 500 or more, and an organic solvent.
