Title:
偏光分離素子
Document Type and Number:
Japanese Patent JP4193591
Kind Code:
B2
Abstract:
A fine particle dispersion composition comprises metal-oxide fine particles; an organic resin material adapted to cure by absorbing energy; one of polyoxyethylene alkyl ether phosphoric acid-based surfactant and a polyoxyethylene alkyl ether carboxylic acid-based surfactant (each having molecular weight of >= 500); and an organic solvent. The composition becomes an optical component when cured. Independent claims are included for the following: (1) an optical film laminate having several stacked optical films that differ in refractive index from one another. The optical film is obtained by curing the fine particle dispersion; (2) a polarization splitting device having a transparent base member having inclined plane surfaces formed in it by grooving, the inclined plane surfaces differing in inclination direction from each other. The inclined plane surfaces has a polarization splitting multilayer film formed on it. The transparent base member and/or the polarization splitting multilayer film is obtained by curing the fine particle dispersion composition; and (3) preparation of optical component involving performing dispersion treatment on metal-oxide fine particles, an organic resin material adapted to cure by absorbing energy; one of polyoxyethylene alkyl ether phosphoric acid-based surfactant and a polyoxyethylene alkyl ether carboxylic acid-based surfactant (each having molecular weight of >=500) in organic solvent together with high hardness metallic balls or ceramic balls; subsequently applying dispersion solution and evaporating the organic solvent.
