A titanium oxide dispersion composition is provides, the composition comprising
a solvent and a titanium oxide with an average secondary particle diameter of 100
nm or smaller, the dispersion composition having a maximum intensity within the
range of from 435 nm to 700 nm of a primary differential spectrum of a transmittance
spectrum, wherein the transmittance spectrum is measured using an ultraviolet-visible
spectrophotometer after adjusting a solid content of the dispersion composition
to be about 2% by weight. The composition provides a film having a high hydrophilicity
under the irradiation of a visible light.
