DISPERSION COMPOSITION, CURABLE COMPOSITION, TRANSPARENT FILM, MICROLENS AND SOLID-STATE IMAGE SENSING DEVICE USING THE SAME, METHOD FOR MANUFACTURING TRANSPARENT FILM, METHOD FOR MANUFACTURING MICROLENS AND METHOD FOR MANUFACTURING SOLID-STATE IMAGE SENSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a dispersion composition which has excellent dispersibility and dispersion stability, has a high refractive index and light transmittance when prepared as a curable composition, and is able to form a film having a small difference in film thickness between the center portion and the peripheral portion thereof even when the composition is applied on a large-size wafer; and to provide a curable composition, a transparent film, a microlens and a solid-state image sensing device using the same, a method for manufacturing a transparent film, a method for manufacturing a microlens and a method for manufacturing a solid-state image sensing device.

SOLUTION: The dispersion composition includes: colorless or transparent metal oxide particles (A) having a primary particle diameter of from 1 to 100 nm; a resin (B1) which has a repeating unit having a group X having a functional group with a pKa of 14 or less, and has an oligomer chain or polymer chain Y having the number of atoms of from 40 to 10,000 in a side chain thereof, and which also contains a basic nitrogen atom; and a solvent (C).
